Введение

Address list segregation is a process whereby administrators can segment their users into separate groups and implement security policies so that groups of users can see only their specific address list. The ability to restrict access to address lists in this manner may be used as part of the toolset for helping companies meet their internal security requirements and as part of a regulatory compliance strategy for meeting the requirements dictated by the Health Insurance Portability and Accountability Act (HIPPA), and the Sarbanes-Oxley Act.

It is useful to illustrate how address list segregation can be implemented by way of examples. Suppose your company, Contoso, purchases the company Fabrikam. The management team determines that they want to manage Fabrikam’s entire IT infrastructure, but they want the employees of Contoso and Fabrikam to be completely segregated so that they can see only other users and resources from their respective companies. By implementing address list segregation, Contoso administrators can meet this requirement for all Exchange Server 2007 functionality.

Another example scenario is one in which Contoso establishes a compliance group to support regulatory compliance efforts for the company. Company management wants this new group not to be visible to any other groups within the company via Microsoft Office Outlook or Outlook Web Access. By implementing address list segregation, Contoso administrators can meet this requirement by correctly configuring Exchange 2007.

Supported and Unsupported Configurations

Supported

Companies that want to completely segregate their address lists can do this by removing access to the Default Global Address List and creating two or more address lists or virtual organizations. You can also set up additional functionality to restrict searching via Outlook Web Access to particular organizational units (OUs) or specific address lists using the msExchQueryBaseDN attribute.

Not Recommended

The configuration described in this document is complex. Although it can be effective in smaller environments or in limited scope, it can become very challenging to manage such a configuration as the scope of the deployment increases if automation steps are not implemented. While you can use scripts like those described in this document to automate the provisioning process, you must plan for failures in your automation process when they occur. The more complex the provisioning scripts, the more difficult it will be to troubleshoot script failures and to determine in what state the failed provisioning request was actually left.

Additionally, you have to make sure that steps are taken to monitor service health in a manner that ensures that all aspects of the services offered by your deployment are proactively monitored to deliver reliable service. This requires not only a well-engineered monitoring infrastructure but also operational expertise and clearly documented processes and procedures to deal with the complexities and challenges that arise when delivering a hosted offering. These issues are not trivial in scope or in expense.

Customers who want to provide a commercial hosting environment should review the Microsoft Hosted Messaging and Collaboration (HMC) solution. This solution addresses the issues described earlier. For more information about the Microsoft HMC solution, see: Microsoft Solution for Hosted Messaging and Collaboration version 4.0.

Unsupported

The information that is provided in this white paper has been tested by the Exchange Product Group at the time that this paper was first published. If you make changes to your environment that are not discussed in this white paper, or if you have applied any service packs or updates to your environment, you may create an unsupported configuration.

This configuration is one in which companies may want to totally segregate their address lists and still have access to the Default Global Address List, or try to split the Global Address List (GAL) into two separate address lists. An example of this configuration would be a company with two groups of 500 users that belong to the Sales and Finance departments. Both groups are in the GAL, however the desire is to have everyone access the GAL except one group. If you are going to segregate your address lists, then they will be segregated. Attempting this configuration will cause problems with the check names functionality which will prevent users from creating Outlook profiles, and can also break the OAB Generation Process. This also allows Outlook users to see all of the Address Lists from within Outlook, which cannot be changed.

It is also important to understand that any attempt to use this white paper to configure Exchange 2007 for a commercial "hosting" solution is not supported. This white paper is not a replacement for the Microsoft HMC (Hosting and Collaboration) software. The information that is provided in this white paper is meant for internal segregation use only.

Planning for Active Directory Partitioning

Примечание.
We recommend that you maintain all virtual organizations in a single forest and domain.

Active Directory partitioning is implemented by creating separate OUs for each virtual organization or group. Each organizational unit will contain the segregated users, distribution lists, and security groups to restrict or grant access to Active Directory appropriately.

As with any Active Directory design, it is important to ensure minimized risk of unauthorized data access. With this design, the risk increases with the use of Internet access and partitioning security. Some risk is due to the fact that Exchange uses the Internet as a primary connection point. If a segregated user is allowed to log on, it has additional methods for accessing the GAL (GAL). Security groups contained within the OUs provide the partitioning security context for the segregated users. These security groups contain only those users who require rights to that specific OU. For example, all users will be restricted to the company's OUs within Active Directory. Some of those users may also be granted additional rights to create new objects (users).

After Exchange is configured to allow access, a security risk is inherent in the creation of new objects. Documented processes must be followed, either manually or programmatically, to ensure that appropriate security is applied to each object. Objects without the correct security context may be able to access objects outside the segregated boundaries. For example, users from one segregated group could potentially have access to user information within another segregated group.

Option 1

Locate all segregated groups in a single forest within a single domain and use OUs to partition each group's users. The advantage of this architecture is that hardware requirements are reduced since all segregated groups are located on the same physical hardware. This option is easy to manage with a single administration process, and is scalable.

A disadvantage of this design is the risk of one segregated group's unintended access to another group's data should the documented permission processes not be followed.

An issue to consider is that Windows Server 2003 adds users and administrators to a default set of security groups, such as the Domain Users group. Disallow this to prevent users from having access to domain resources, such as printers. This will not prevent you from allowing users and administrators to access resources found only in Exchange.

Option 2

Locate all segregated groups in a single forest with multiple domains. Each segregated group stores user data in a separate domain, and the global catalog would provide information from the directory.

A disadvantage of this architecture is cost. Locating each segregated group in a separate domain requires at least two domain controllers per segregated group and you must still implement processes to prevent the issues detailed above with the single domain method. Because security settings and defaults apply to a domain, the impact of a user being added to a Windows Server 2003 security group, such as Domain Users, is limited to the segregated groups in that domain.

Option 3

Locate each segregated group in a separate forest partition where each group's users are located in a separate Active Directory schema. An advantage of this method is minimal risk of inadvertently giving one segregated group access to another group's data. Distributing services across hardware offers other advantages. In the event of a failure, you can continue to provide services to other companies while restoring services to the affected company.

A drawback of this design is cost. To locate each segregated group in a separate forest requires at least two domain controllers per group, separate administration processes, and disaster recovery equipment. You will also have to manage each and every forest as a completely separate entity. This approach is generally not practical because of the additional hardware and administrative cost.

Global Address List Configuration

Active Directory contains a database of all users. The practical implementation of this database, when accessed from an Outlook client, is referred to as the Exchange GAL. When segregating Exchange, if user searches this list, you want to limit the results to recipients in the same segregated group.

This partitioning of the GAL is provided by access control lists associated with global group memberships. For each organizational unit containing a segregated group, a global group must be created. The global group membership is the users of the segregated group located in the OU. Use this group, together with other permission changes, to provide a view of Active Directory specific to the segregated group located in the organizational unit.

When partitioning the GAL, you must remove the existing default rights to see all users and objects within Active Directory. To accomplish this task, you must remove from each organizational unit the permissions assigned to the Authenticated Users group and the Everyone group, if it exists.

The host company requires permissions to see all objects within Active Directory. Add rights for the security group for each segregated group's users, thus allowing the users to see other users in their own organizational unit. Go through each organizational unit and add a security group for that segregated group. For example, for the organizational unit representing Fabrikam.com, add the Fabrikam Users security group and assign Read rights.

There are some permissions that apply only to specific clients. Your service determines which clients get support. For example, Outlook Web Access does not incorporate user permission sets when doing searches. The permissions set on OUs do not prevent search results from including other segregated group's recipients. If you are using Outlook Web Access, you must set the attribute msExchQueryBaseDN on each address list or user object to restrict the search results to include only the members of the appropriate address list.

As with all security and permissions changes, verification and testing must be performed to ensure the expected result is obtained after the change has been implemented. In this example, the Outlook client and Outlook Web Access should be tested to guarantee that each segregated group can view only their group-specific data, and that all client features operate as intended.

msExchUserOAB Configuration

When you configure multiple offline address lists for a particular messaging database (MDB) in Exchange, Exchange associates the offline address book that a user is permitted to download with the MDB where that user's mailbox is located. This may be unacceptable if you locate many segregated groups on a single mailbox database. Modification of the user attribute msExchUseOAB will allow Exchange to determine the offline address book (that is generated from a particular address list, or lists), and is meant to be available to each user. When you must locate multiple segregated groups on a single database, and these groups have different offline address lists, you must restrict the offline address book by using the msExchUseOAB attribute.

msExchQueryBasedDN Configuration

Microsoft Outlook Web Access (OWA) users may use the Find names feature to view users, including those who are not located in the same organizational unit. To limit the scope of a directory service search available to Outlook Web Access users, you must set the msExchQueryBaseDN attribute on each user object. The value that is specified for the msExchQueryBaseDN attribute limits the searches and the ambiguous name resolution queries that a user can perform. This can be set to the distinguishedname (DN) of the OU or an address list containing the correct group of users.

dsHeuristics Configuration

Active Directory in earlier versions of Microsoft Windows-based domains accept anonymous requests. In these versions, a successful result depends on having correct user permissions in Active Directory.

With Windows Server 2003, only authenticated users may initiate an LDAP request against Windows Server 2003-based domain controllers. You can override this new default behavior by changing the third character of the dsHeuristics attribute. By default, this attribute is not set. If the attribute is not set, you must change the value to 001. If the attribute is already populated, change the third character to a 1 and leave the first two as they are. The DN path for the dsHeuristics attribute is listed below. It can be found in the root domain of the forest.

CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration

The dsHeuristics setting applies to all Windows Server 2003-based domain controllers in the same forest. The value is realized by domain controllers upon Active Directory replication without restarting Windows.

Примечание.
Microsoft Windows 2000 Server-based domain controllers do not support this setting and do not restrict anonymous operations if they are present in a Windows Server 2003-based forest.

Важно!

In Active Directory, object visibility is normally controlled by List Contents permissions on the parent object, which is an object that will only be visible to a user if the user has been granted List Contents permissions on the parent object. When a user has List Contents permission on a parent node, he or she can see and browse all objects that are children of that node without any further selectivity. However, Active Directory can also be configured to control object visibility at a more granular level on a per-object basis. This is a special mode referred to as the "List Object" mode. In this special mode, an object will continue to be visible to a user if the user has been granted List Contents permission on the parent object. Alternatively, if the user has not explicitly been granted or explicitly been denied List Contents permission on the parent object, the object will still be visible to the user if the user is granted List Object permission on both the parent object and the object itself. When considering the use of this special "List Object" mode for Active Directory, it is important to keep in mind that controlling object visibility purely based on the List Object permission will significantly increase the number of access check calls made by the directory service to determine if an object is visible to a user. Therefore, it can have a negative effect on the performance of browsing or reading from Active Directory. The directory can be put in this special "List Object" mode by modifying the dsHeuristics attribute on the Directory Service object (cn=Directory Service,cn=Windows NT,cn=Services,cn=Configuration,dc=ForestRootDomain). This attribute is a single valued Unicode string and the third character position (from the left) which controls whether or not the directory service is in the special "List Object" mode. The default value for the third character is 0. Changing the third character value to 1 will put the directory service in the special "List Object" mode. By default, only Enterprise Administrators and Domain Administrators of the Root Domain have permissions to modify this attribute. Care should be taken when changing this dsHeuristics attribute value because other characters in this value control other directory service functionality. Accidentally modifying them might directly affect functionality.

User Principal Name Configuration

User principal names (UPNs) provide logon names in a format similar to e-mail names. By making UPN values independent from domain names, you can move user accounts between domains while leaving UPN values unchanged, making the move transparent to users and easing administration.

The primary benefit of using UPNs is to provide a unique namespace for each segregated organization. Through the use of UPN for logon and user identification, rob@contoso.com and rob@fabrikam.com can be supported in the same Active Directory domain without worrying about Rob’s user ID or e-mail name being unique. Each segregated group can be provided a unique namespace, which is equivalent to how most companies allocate user credentials. This also masks the Windows domain name from the segregated users who have this attribute configured. This provides the appearance to each segregated group that the entire environment is set up purely for them, even though several virtual organizations have been segregated within your environment.

The main advantage to using UPNs is for Outlook Web Access or IMAP logons. This enables users to log on to their mailboxes, using only their SMTP address and password, without specifying a Windows 2003 domain.

Configuring a Segregated Organization

When you use Exchange 2007 to segregate different companies or divisions under one Exchange infrastructure, you must create multiple address lists, GALs and offline address lists. The address lists typically have different user accounts listed in them based on the filters that you create. By default, all the users in the Exchange 2007 organization can view all the defined GALs. This may not be acceptable in some cases; for example, it would not be acceptable at a company that has multiple divisions that are required by law to ensure that the data for each division remain completely separated. This issue can be overcome by restricting access to a particular set of users for specific address lists, GALs and offline address lists.

Preparing Your Environment for Segregated Exchange

Важно!
A prerequisite to deploying the configuration described in this document is the installation of Exchange 2007 SP1.

In this section, you will use the Exchange Management Console, the Exchange Management Shell, ADSIEdit (AdsiEdit.msc), and Active Directory Users and Computers to prepare Active Directory to host segregated information. This approach allows for easy configuration and administration of your segregated environment because it provides very clearly defined security boundaries. This section contains the following procedures:

• Set the dsHeuristics value

• Create an Organizational Unit to contain all segregated virtual organization OUs

• Modify permissions on the All Address Lists container

• Delete the default Address Lists

• Restrict Access to the Default Global Address List

• Restrict Access to the Offline Address Lists container

• Create a Security Group for all Hosted Groups

When you have prepared the environment, you can leverage Windows PowerShell scripting to automate the provisioning of additional virtual companies and their users. By scripting these functions, you can reduce the possibility of human error in the provisioning process. We recommend that administrators become familiar with the manual provisioning process for virtual companies and users in a lab environment before creating scripts. Familiarity with the individual steps will make troubleshooting issues much easier. Sample PowerShell scripts are provided in the "Automating the Creation of Virtual Companies and Users" section of this document.

Set the dsHeuristics Value

To configure the dsHeuristics value using ADSIEdit, use the following procedure:

Before You Begin

To perform the following procedures, the account you use must be a member of the Domain Administrators group.

   2. All Groups

   3. All Rooms

   4. All Users

   5. Public Folders

6. Right click and select Remove or click the Remove action item.

7. Click Yes to confirm the deletion.

Restrict Access to the Default Global Address List

Use the following procedure to modify the security permissions for the default GAL that is created when Exchange 2007 is installed. It is important to modify the security settings, rather than delete the default GAL, to ensure that Exchange can have access to the GAL when necessary but that segregated users cannot see the default GAL entries, which include all users by default.

Before You Begin

To perform the following procedures, the account you use must be delegated the Exchange Server Administrator role and membership in the local Administrators group on the target server.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Вопросы, связанные с разрешениями.

Procedure

To use the Exchange Management Shell to modify the security permissions on the Default Global Address List for the Authenticated Users group

1. Run the following command:

   Get-GlobalAddressList "Default Global Address List" | Add-ADPermission -User "Authenticated Users" -AccessRights GenericRead -ExtendedRights Open-Address-Book -Deny:$True
   

2. Press Enter to confirm the removal of the permissions.

   Примечание.
   The default response is Yes. By pressing Enter you are accepting the default.

   Примечание.
   Optionally, you can run the following commands to validate that the permissions have been correctly applied.

3. Run the following command:

   $galContainer = "CN=All Global Address Lists,CN=Address Lists Container,CN=<OrganizationName>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=contoso,DC=com"
   

   Примечание.
   You must modify the example DN to reflect the DN for your Default Global Address Lists container. Normally only the "DC" entries need to be modified if the Exchange installation was a "default" installation.

4. Run the following command:

   Get-ADPermission $galContainer -user "authenticated users"
   

   Примечание.
   The output should resemble this:

   Identity                       User                    Deny  Rights

   \Global Address List       NT AUTHORITY\Authenticated Users     True   Open-Address-Book

   \Global Address List      NT AUTHORITY\Authenticated Users      True   ReadProperty

   \\Global Address List      NT AUTHORITY\Authenticated Users     True   ListObject, GenericExecute

Restrict Access to the Offline Address Lists Container

Use the following procedure to modify the security permissions for the Offline Address Lists container that is created when Exchange 2007 is installed.

Before You Begin

To perform the following procedures, the account you use must be delegated the Exchange Server Administrator role and membership in the local Administrators group on the target server.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Вопросы, связанные с разрешениями.

Procedure

Create a Security Group for all Hosted Groups

Use the following procedure to create an "All Hosted Groups" security group for all of your virtual organization security groups. This group will be added to the security permissions for the CN=Address Lists Container. With this configuration in place, users will only be able to view address lists that their security group allows them access to when they are using Outlook and they click on the address list icon on the menu bar.

Before You Begin

To perform the following procedures, the account you use must be delegated the following:

• Exchange Recipient Administrator role

• Account Operator role for the applicable Active Directory containers

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Вопросы, связанные с разрешениями.

Важно!
If you want to create a new security group in a domain that is different than the one in which your Exchange servers reside, you must first prepare that domain for Exchange 2007. To learn more about preparing a domain for Exchange 2007, see Инструкции по подготовке службы Active Directory и доменов.

To use the Exchange Management Shell to create a security group and apply security to the settings to the security group

1. Run the following command:

   New-DistributionGroup -Name "All Hosted Groups SG" -OrganizationalUnit "Contoso.com/Companies" -SamAccountName "AllHostedGroupsSG" -Alias "AllHostedGroupsSG" -Type "Security"
   

2. Run the following command:

   Add-ADPermission -Identity "CN=Address Lists Container,CN=Contoso,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=Contoso,DC=com" -User "All Hosted Groups SG" -AccessRights GenericRead -Deny
   

   Примечание.
   You must modify the example DN to reflect the DN for your Address Lists container. Normally only the "DC" entries need to be modified if the Exchange installation was a "default" installation.

3. Run the following command:

Create a New Accepted Domain

You must configure an accepted domain before that SMTP namespace can be used in an e-mail address policy. The accepted domain is automatically populated to the e-mail address policy editor. Each domain or subdomain that you want to use as part of an e-mail address policy must have an explicit accepted domain entry.

Before You Begin

Accepted domains are configured on computers that have the Hub Transport server role installed and on computers that have the Edge Transport server role installed. We recommend that you configure accepted domains only on the Hub Transport server role and then populate that data on the Edge Transport server by using the Edge Subscription process. When the Edge Subscription process runs, the accepted domain configuration information is replicated to the subscribed Edge Transport server. For more information, see Подписывание сервера граничного транспорта на организацию Exchange.

Примечание.
Do not perform this procedure on an Edge Transport server that has been subscribed to the Exchange organization by using EdgeSync. Instead, create the accepted domain on the Hub Transport server. It will be replicated to the Edge Transport server when synchronization next occurs.

To perform the following procedures, the account you use must be delegated the Exchange Organization Administrator role.

To perform the following procedures on a computer that has the Edge Transport server role installed, you must log on by using an account that is a member of the local Administrators group on that computer.

Важно!
The accepted domain cannot also exist as a remote domain.

Важно!
You cannot modify the default accepted domain. To change which accepted domain is the default accepted domain, you must create a new accepted domain, and then set the new accepted domain as the default by using the Exchange Management Shell. For more information, see New-AcceptedDomain and Set-AcceptedDomain.

Procedure

To use the Exchange Management Shell to create an accepted domain

• Run the following command to create an authoritative domain:

  New-AcceptedDomain -Name "Fabrikam" -DomainName "Fabrikam.com" -DomainType Authoritative -domaincontroller "dc1"
  

To use the Exchange Management Console to create an accepted domain

1. Open the Exchange Management Console.

2. In the console tree, expand Organization Configuration, select Hub Transport, and then in the work pane, click the Accepted Domains tab.

3. In the action pane, click New Accepted Domain… The New Accepted Domain wizard appears.

Automating the Creation of Virtual Companies and Users

The Exchange Management Shell makes scripting most of the Company and User creation processes described above very simple. You can also script the Company removal process in the event that a virtual company needs to be removed from the environment.

The NewCompany.ps1 sample script provided below will automate the creation of the Organizational Unit, Security Group, AcceptedDomain, EmailAddressPolicy, AddressList, GAL, and the Offline Address Book.

The script can be easily modified to make it usable in your environment. The script will prompt the administrator to enter a Company Name, Company Domain, and a domain controller name.

Примечание.
The Company Domain refers to the SMTP address not the Windows domain name.

The NewUser.ps1 sample script provided below will automate the creation of the user object and mailbox as well as setting all of the required attributes. The script can be easily modified to make it usable in your environment. The script will prompt the administrator to enter a Company Name, a domain controller name, New User First Name, New User Last Name, and the UPN address for the user.

The DeleteCompany.ps1 sample script provided below will automate the process of removing a virtual company from your environment.

NewCompany.ps1

In order to make the NewCompany.ps1 script functional in your specific environment, it must be modified as described in the script remarks. This script will automate all of the steps required to provision a new company and will create a confirmation html page that details the results of the steps taken.

NewUser.ps1

The following sample script must be modified as described in the script remarks in order to make it functional in your specific environment. This script will automate all of the steps required to provision a user for a specific a virtual company in your environment. We recommend that you create a new script for user creation for each virtual company that you host. To ensure that the appropriate script is run, you should name each script with a descriptive name like NewContosoUser.ps1.

Before You Begin

To perform this procedure, the account you use must be delegated the Exchange Recipient Administrator role.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Вопросы, связанные с разрешениями.

3. Modify the script to make it functional in your environment as detailed in the script remarks.

4. Move the script to the location containing the Exchange Server scripts. By default these are located at c:\Program Files\Microsoft\Exchange Server\Scripts\

5. Start the Exchange Management Shell.

6. Run the following command:

   New<Company>User.ps1
   

   Примечание.
   If you have named the script something other than New<Company>User.ps1, enter that name instead of New<Company>User.ps1.

7. Enter the appropriate company name, the user’s first name, the user’s last name, and the User Principal Name (UPN) when you are prompted.

When you test a user account after you create the new company and users, you should use a computer that is not logged on using the same administrator credentials as those used by the server. For example, do not perform an OWA test from the server on which you created the company and users. This practice helps prevent an issue in which you pass to Exchange the credentials for the local administrator account instead of the credentials for the user account that you are trying to test.

DeleteCompany.ps1

The following sample script must be modified as described in the script remarks in order to make it functional in your specific environment. This script will automate most of the steps required to remove a virtual company from your environment. For data protection purposes, the script will not delete the actual customer data contained in the virtual companies OU or remove the OU itself. Those steps should be performed manually.

Before You Begin

To perform this procedure, the account you use must be delegated the Exchange Recipient Administrator role.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Вопросы, связанные с разрешениями.

Procedure

To use Exchange Management Shell scripting to automate the removal of a virtual company from your Exchange environment

1. Open Notepad or another text editor.

2. Copy the following code into a file and save the file with a descriptive name and the .ps1 extension. It is recommended to name the file DeleteCompany.ps1.
