Description

The Set-ADUser cmdlet modifies the properties of an Active Directory user. You can modify commonly used property values by using the cmdlet parameters. You can set property values that are not associated with cmdlet parameters by using the Add, Remove, Replace, and Clear parameters.

The Identity parameter specifies the Active Directory user to modify. You can identify a user by its distinguished name, GUID, security identifier (SID), or Security Account Manager (SAM) account name. You can also set the Identity parameter to an object variable such as $<localUserObject>, or you can pass an object through the pipeline to the Identity parameter. For example, you can use the Get-ADUser cmdlet to retrieve a user object and then pass the object through the pipeline to the Set-ADUser cmdlet.

The Instance parameter provides a way to update a user object by applying the changes made to a copy of the object. When you set the Instance parameter to a copy of an Active Directory user object that has been modified, the Set-ADUser cmdlet makes the same changes to the original user object. To get a copy of the object to modify, use the Get-ADUser object. The Identity parameter is not allowed when you use the Instance parameter. For more information about the Instance parameter, see the Instance parameter description.

Accounts created with the New-ADUser cmdlet are disabled if no password is provided.

For AD LDS environments, the Partition parameter must be specified except in the following two conditions:

• The cmdlet is run from an Active Directory provider drive.
• A default naming context or partition is defined for the AD LDS environment. To specify a default naming context for an AD LDS environment, set the msDS-defaultNamingContext property of the Active Directory directory service agent object (nTDSDSA) for the AD LDS instance.

Examples

Example 1: Set properties for a user

$params = @{
    Identity          = 'ChewDavid'
    HomePage          = 'http://fabrikam.com/employees/ChewDavid'
    LogonWorkstations = 'ChewDavid-DSKTOP,ChewDavid-LPTOP'
}
Set-ADUser @params

This command sets the specified user's homepage property to http://fabrikam.com/employees/ChewDavid and the LogonWorkstations property to ChewDavid-DSKTOP,ChewDavid-LPTOP.

Example 2: Set properties for multiple users

PS C:\> Get-ADUser -Filter 'Name -like "*"' -SearchBase 'OU=HumanResources,OU=UserAccounts,DC=FABRIKAM,DC=COM' -Properties DisplayName | % {Set-ADUser $_ -DisplayName ($_.Surname + ' ' + $_.GivenName)}

This command gets all the users in the directory that are located in the OU=HumanResources,OU=UserAccounts,DC=FABRIKAM,DC=COM organizational unit. The command sets the DisplayName property on these user objects to the concatenation of the Surname property and the GivenName property.

Example 3: Set properties

PS C:\> Set-ADUser -Identity GlenJohn -Replace @{title="director";mail="glenjohn@fabrikam.com"}

This command sets the specified user's title property to director and the mail property to glenjohn@fabrikam.com.

Example 4: Modify a user otherMailbox property

PS C:\> Set-ADUser -Identity GlenJohn -Remove @{otherMailbox="glen.john"} -Add @{url="fabrikam.com"} -Replace @{title="manager"} -Clear description

This command modifies the user with the SAM account name GlenJohn's object by removing glen.john from the otherMailbox property, adding fabrikam.com to the url property, replacing the title property with manager, and clearing the description property.

Example 5: Set user properties to a local instance

PS C:\> $User = Get-ADUser -Identity GlenJohn -Properties mail,department
PS C:\> $User.mail = "glen@fabrikam.com"
PS C:\> $User.department = "Accounting"
PS C:\> Set-ADUser -Instance $User

This example sets the mail and department properties on the user object with the SAM account name GlenJohn by using the Instance parameter.

Example 6: Set attributes for a user

PS C:\> $Hours = New-Object byte[] 21
PS C:\> $Hours[5] = 255; $Hours[8] = 255; $Hours[11] = 255; $Hours[14] = 255; $Hours[17] = 255;
PS C:\> $Hours[6] = 1; $Hours[9] = 1; $Hours[12] = 1; $Hours[15] = 1; $Hours[18] = 1;
PS C:\> $ReplaceHashTable = New-Object HashTable
PS C:\> $ReplaceHashTable.Add("logonHours", $Hours)
PS C:\> $ReplaceHashTable.Add("description", "Sarah Davis can only logon from Monday through Friday from 8:00 AM to 5:00 PM")
PS C:\> Set-ADUser -Identity "SarahDavis" -Replace $ReplaceHashTable

This example sets the user logon hours to Monday through Friday from 8:00 AM to 5:00 PM and adds a description. It updates the logonHours attribute with the specified byte array and the description attribute with the specified string.

Example 7: Set a property for a user

PS C:\> $Manager = Get-ADUser -Identity GlenJohn -Server Corp-DC01
PS C:\> Set-ADUser -Identity ChewDavid -Manager $Manager -Server Branch-DC02

This example sets the Manager property for the user with the SAM account name of ChewDavid where the manager, GlenJohn, is a user in another domain.

Example 8: Get a user and set a property

PS C:\> Get-ADUser -Identity "DavidChew" | Set-ADUser -Manager "ElisaDaugherty"

This command modifies the Manager property for the DavidChew user. The command uses the Get-ADUser cmdlet to get the user DavidChew, and then passes the object to the current cmdlet by using the pipeline operator.

None removes all encryption types from the account, resulting in the KDC being unable to issue service tickets for services using the account.

DES is a weak encryption type that is not supported by default since Windows 7 and Windows Server 2008 R2.

Warning

Domain-joined Windows systems and services such as clustering manage their own msDS-SupportedEncryptionTypes attribute. Therefore any changes to the flag on the msDS-SupportedEncryptionTypes attribute are overwritten by the service or system that manages the setting.

-Partition

Specifies the distinguished name of an Active Directory partition. The distinguished name must be one of the naming contexts on the current directory server. The cmdlet searches this partition to find the object defined by the Identity parameter.

In many cases, a default value is used for the Partition 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 when a default value can be determined, no further rules are evaluated.

In AD DS environments, a default value for Partition are set in the following cases:

• If the Identity parameter is set to a distinguished name, the default value of Partition is automatically generated from this distinguished name.
• If running cmdlets from an Active Directory provider drive, the default value of Partition is automatically generated from the current path in the drive.
• If none of the previous cases apply, the default value of Partition is set to the default partition or naming context of the target domain.

In AD LDS environments, a default value for Partition will be set in the following cases:

• If the Identity parameter is set to a distinguished name, the default value of Partition is automatically generated from this distinguished name.
• If running cmdlets from an Active Directory provider drive, the default value of Partition is automatically generated from the current path in the drive.
• If the target AD LDS instance has a default naming context, the default value of Partition is 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 object (nTDSDSA) for the AD LDS instance.
• If none of the previous cases apply, the Partition parameter does not take any default value.
