Detailed Description

The New-ADServiceAccount cmdlet creates a new Active Directory service account. You can set commonly used service account property values by using the cmdlet parameters. Property values that are not associated with cmdlet parameters can be set by using the OtherAttributes parameter.

The Path parameter specifies the container or organizational unit (OU) for the new service account object. When you do not specify the Path parameter, the cmdlet creates an object in the default container for service account objects in the domain.

The following methods explain different ways to create an object by using this cmdlet.

Method 1: Use the New-ADServiceAccount cmdlet, specify the required parameters, and set any additional property values by using the cmdlet parameters.

Method 2: Use a template to create the new object. To do this, create a new service account object or retrieve a copy of an existing service account object and set the Instance parameter to this object. The object provided to the Instance parameter is used as a template for the new object. You can override property values from the template by setting cmdlet parameters. For examples and more information, see the Instance parameter description for this cmdlet.

Method 3: Use the Import-CSV cmdlet with the New-ADServiceAccount cmdlet to create multiple Active Directory service account objects. To do this, use the Import-CSV cmdlet to create the custom objects from a comma-separated value (CSV) file that contains a list of object properties. Then pass these objects through the pipeline to the New-ADServiceAccount cmdlet to create the service account objects.

Parameters

AccountExpirationDate

Specifies the expiration date for an account. When you set this parameter to 0, the account never expires. This parameter sets the AccountExpirationDate property of an account object. The LDAP Display name (ldapDisplayName) for this property is accountExpires.

Use the DateTime syntax when you specify this parameter. Time is assumed to be local time unless otherwise specified. When a time value is not specified, the time is assumed to 12:00:00 AM local time. When a date is not specified, the date is assumed to be the current date. The following examples show commonly-used syntax to specify a DateTime object.
"4/17/2006"
"Monday, April 17, 2006"
"2:22:45 PM"
"Monday, April 17, 2006 2:22:45 PM"

These examples specify the same date and the time without the seconds.
"4/17/2006 2:22 PM"
"Monday, April 17, 2006 2:22 PM"
"2:22 PM"

The following example shows how to specify a date and time by using the RFC1123 standard. This example defines time by using Greenwich Mean Time (GMT).
"Mon, 17 Apr 2006 21:22:48 GMT"

The following example shows how to specify a round-trip value as Coordinated Universal Time (UTC). This example represents Monday, April 17, 2006 at 2:22:48 PM UTC.
"2006-04-17T14:22:48.0000000"

The following example shows how to set this parameter to the date May 1, 2012 at 5 PM.
-AccountExpirationDate "05/01/2012 5:00:00 PM"

AccountNotDelegated

Specifies whether the security context of the user is delegated to a service. When this parameter is set to true, the security context of the account is not delegated to a service even when the service account is set as trusted for Kerberos delegation. This parameter sets the AccountNotDelegated property for an Active Directory account. This parameter also sets the ADS_UF_NOT_DELEGATED flag of the Active Directory User Account Control (UAC) attribute. Possible values for this parameter include
$false or 0
$true or 1

The following example shows how to set this parameter so that the security context of the account is not delegated to a service.
-AccountNotDelegated $true

AccountPassword

Specifies a new password value for an account. This value is stored as an encrypted string.

The following conditions apply based on the manner in which the password parameter is used:

$null password is specified - Random password is set and the account is enabled unless it is requested to be disabled
No password is specified - Random password is set and the account is enabled unless it is requested to be disabled

User password is specified - Password is set and the account is enabled unless it is requested to be disabled, unless the password you provided does not meet password policy or was not set for other reasons, at which point the account is disabled

Notes: Service accounts, by default, are created with a 240-character random password. If you provide a password, an attempt will be made to set that password however, this can fail due to password policy restrictions. The service account will still be created and you can use Set-ADAccountPassword to set the password on that account. In order to ensure that accounts remain secure, service accounts will never be enabled unless a valid password is set (either a randomly-generated or user-provided one) or PasswordNotRequired is set to true.

The new ADServiceAccount object will always either be disabled or have a user-requested or randomly-generated password. There is no way to create an enabled service account object with a password that violates domain password policy, such as an empty password.
The account is created if the password fails for any reason.

The following example shows how to set this parameter. This command will prompt you to enter the password.
-AccountPassword (Read-Host -AsSecureString "AccountPassword")

Certificates

Modifies the DER-encoded X.509v3 certificates of the account. These certificates include the public key certificates issued to this account by the Microsoft Certificate Service. This parameter sets the Certificates property of the account object. The LDAP Display Name (ldapDisplayName) for this property is "userCertificate".

Syntax:
To add values:
-Certificates @{Add=value1,value2,...}
To remove values:
-Certificates @{Remove=value3,value4,...}
To replace values:
-Certificates @{Replace=value1,value2,...}
To clear all values:
-Certificates $null

You can specify more than one operation by using a list separated by semicolons. For example, use the following syntax to add and remove Certificate values
-Certificates @{Add=value1,value2,...};@{Remove=value3,value4,...}

The operators will be applied in the following sequence:
..Remove
..Add
..Replace

The following example shows how to create a certificate by using the New-Object cmdlet, and then add it to a user account. When this cmdlet is run, <certificate password> is replaced by the password used to add the certificate.

$cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate certificate1.cer <certificate password>
Set-ADUser saradavis -Certificates @{Add=$cert}

The following example shows how to add a certificate that is specified as a byte array.

Credential

Specifies the user account credentials to use to perform this task. The default credentials are the credentials of the currently logged on user unless the cmdlet is run from an Active Directory PowerShell provider drive. If the cmdlet is run from such a provider drive, the account associated with the drive is the default.

To specify this parameter, you can type a user name, such as "User1" or "Domain01\User01" or you can specify a PSCredential object. If you specify a user name for this parameter, the cmdlet prompts for a password.

You can also create a PSCredential object by using a script or by using the Get-Credential cmdlet. You can then set the Credential parameter to the PSCredential object The following example shows how to create credentials.
$AdminCredentials = Get-Credential "Domain01\User01"

The following shows how to set the Credential parameter to these credentials.
-Credential $AdminCredentials

If the acting credentials do not have directory-level permission to perform the task, Active Directory PowerShell returns a terminating error.

Instance

Specifies an instance of a service account object to use as a template for a new service account object.

You can use an instance of an existing service account object as a template or you can construct a new service account object for template use. You can construct a new service account using the Windows PowerShell command line or by using a script. The following examples show how to use these two methods to create service account object templates.

Method 1: Use an existing service account object as a template for a new object. To retrieve an instance of an existing service account object, use a cmdlet such as Get-ADServiceAccount. Then provide this object to the Instance parameter of the New-ADServiceAccount cmdlet to create a new service account object. You can override property values of the new object by setting the appropriate parameters.

$serviceaccountInstance = Get-ADServiceAccount -Identity
New-ADServiceAccount -Name "ServiceAdmin_2" -Instance $serviceaccountInstance -Description "Service Account 2"

Method 2: Create a new ADServiceAccount object and set the property values by using the Windows PowerShell command line interface. Then pass this object to the Instance parameter of the New-ADServiceAccount cmdlet to create the new Active Directory service account object.

$serviceaccountInstance = new-object Microsoft.ActiveDirectory.Management.ADServiceAccount
$serviceaccountInstance. Description "Service Account 2"

Note: Specified attributes are not validated, so attempting to set attributes that do not exist or cannot be set will raise an error.

OtherAttributes

Specifies object attribute values for attributes that are not represented by cmdlet parameters. You can set one or more parameters at the same time with this parameter. If an attribute takes more than one value, you can assign multiple values. To identify an attribute, specify the LDAPDisplayName (ldapDisplayName) defined for it in the Active Directory schema.

Syntax:
To specify a single value for an attribute:
-OtherAttributes @{'AttributeLDAPDisplayName'=value}
To specify multiple values for an attribute
-OtherAttributes @{'AttributeLDAPDisplayName'=value1,value2,...}

You can specify values for more than one attribute by using semicolons to separate attributes. The following syntax shows how to set values for multiple attributes:
-OtherAttributes @{'Attribute1LDAPDisplayName'=value; 'Attribute2LDAPDisplayName'=value1,value2;...}

The following examples show how to use this parameter.

To set the value of a custom attribute called favColors that takes a set of Unicode strings, use the following syntax:
-OtherAttributes @{'favColors'="pink","purple"}

To set values for favColors and dateOfBirth simultaneously, use the following syntax:
-OtherAttributes @{'favColors'="pink","purple"; 'dateOfBirth'=" 01/01/1960"}

Path

Specifies the X.500 path of the Organizational Unit (OU) or container where the new object is created.

In many cases, a default value will be used for the Path parameter if no value is specified. The rules for determining the default value are given below. Note that rules listed first are evaluated first and once a default value can be determined, no further rules will be evaluated.

In AD DS environments, a default value for Path will be set in the following cases:
- If the cmdlet is run from an Active Directory PowerShell provider drive, the parameter is set to the current path of the provider drive.
- If the cmdlet has a default path, this will be used. For example: in New-ADUser, the Path parameter would default to the Users container.
- If none of the previous cases apply, the default value of Path will be set to the default partition or naming context of the target domain.

In AD LDS environments, a default value for Path will be set in the following cases:
- If the cmdlet is run from an Active Directory PowerShell provider drive, the parameter is set to the current path of the provider drive.
- If the cmdlet has a default path, this will be used. For example: in New-ADUser, the Path parameter would default to the Users container.
- If the target AD LDS instance has a default naming context, the default value of Path will be set to the default naming context. To specify a default naming context for an AD LDS environment, set the msDS-defaultNamingContext property of the Active Directory directory service agent (DSA) object (nTDSDSA) for the AD LDS instance.
- If none of the previous cases apply, the Path parameter will not take any default value.

The following example shows how to set this parameter to an OU.

-Path "ou=mfg,dc=noam,dc=corp,dc=contoso,dc=com"

Note: The Active Directory Provider cmdlets, such New-Item, Remove-Item, Remove-ItemProperty, Rename-Item and Set-ItemProperty also contain a Path property. However, for the provider cmdlets, the Path parameter identifies the path of the actual object and not the container as with the Active Directory cmdlets.

Specifies the Security Account Manager (SAM) account name of the user, group, computer, or service account. The maximum length of the description is 256 characters. To be compatible with older operating systems, create a SAM account name that is 20 characters or less. This parameter sets the SAMAccountName for an account object. The LDAP display name (ldapDisplayName) for this property is "sAMAccountName".

The following example shows how to specify this parameter.
-SAMAccountName "saradavis"

Example: corp-DC12.corp.contoso.com
NetBIOS name
Example: corp-DC12
Fully qualified directory server name and port
Example: corp-DC12.corp.contoso.com:3268

The default value for the Server parameter is determined by one of the following methods in the order that they are listed:
-By using Server value from objects passed through the pipeline.
-By using the server information associated with the Active Directory PowerShell provider drive, when running under that drive.
-By using the domain of the computer running Powershell.

The following example shows how to specify a full qualified domain name as the parameter value.
-Server "corp.contoso.com"

ServicePrincipalNames

Specifies the service principal names for the account. This parameter sets the ServicePrincipalNames property of the account. The LDAP display name (ldapDisplayName) for this property is servicePrincipalName. This parameter uses the following syntax to add remove, replace or clear service principal name values.
Syntax:
To add values:
-ServicePrincipalNames @{Add=value1,value2,...}
To remove values:
-ServicePrincipalNames @{Remove=value3,value4,...}
To replace values:
-ServicePrincipalNames @{Replace=value1,value2,...}
To clear all values:

You can specify more than one change by using a list separated by semicolons. For example, use the following syntax to add and remove service principal names.
@{Add=value1,value2,...};@{Remove=value3,value4,...}

The operators will be applied in the following sequence:
..Remove
..Add
..Replace

The following example shows how to add and remove service principal names.
