Description

The Set-ADServiceAccount cmdlet modifies the properties of an Active Directory managed service account (MSA). You can modify commonly used property values by using the cmdlet parameters. Property values that are not associated with cmdlet parameters can be modified by using the Add, Remove, Replace, and Clear parameters.

The Identity parameter specifies the Active Directory MSA to modify. You can identify an MSA 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 $<localServiceAccountObject>, or you can pass an object through the pipeline to the Identity parameter. For example, you can use the Get-ADServiceAccount cmdlet to retrieve a MSA object and then pass the object through the pipeline to the Set-ADServiceAccount cmdlet.

The Instance parameter provides a way to update an MSA 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 MSA object that has been modified, the Set-ADServiceAccount cmdlet makes the same changes to the original MSA object. To get a copy of the object to modify, use the Get-ADServiceAccount object. When you specify the Instance parameter you should not pass the Identity parameter. For more information about the Instance parameter, see the Instance parameter description.

Examples

Example 1: Set the description for an MSA

PS C:\> Set-ADServiceAccount -Identity Service1 -Description "Secretive Data Server"

This command sets the description of the MSA identified as Service1 to Secretive Data Server.

Example 2: Replace the value of a property for an MSA

PS C:\> Set-ADServiceAccount -Identity Mongol01ADAM -ServicePrincipalNames @{replace="ADAMwdb/a.contoso.com", "ADAMbdb/a.contoso.com"}

This command replaces the value of property ServicePrincipalNames with ADAMwdb/a.contoso.com, ADAMbdb/a.contoso.com.

Example 3: Set the principals allowed to retrieve the password for an MSA

PS C:\> Set-ADServiceAccount -Identity Service1 -PrincipalsAllowedToRetrieveManagedPassword "MsaAdmins.corp.contoso.com"

This command sets the principals allowed to retrieve the password for this MSA to be limited to members of the specified Active Directory group account.

Example 4: Set the ServicePrincipalNames property

PS C:\> Set-ADServiceAccount -Identity AccessTSQA -ServicePrincipalNames @{Add=ACCESSAPP/TSQA.contoso.com}

This command modifies the ServicePrincipalNames property for the AccessTSQA MSA by specifying the Identity and ServicePrincipalNames parameters.

Example 5: Get a specified MSA and modify its ServicePrincipalNames property

PS C:\> Get-ADServiceAccount -Identity "AccessTSQA" | Set-ADServiceAccount -ServicePrincipalNames @{Add=ACCESSAPP/TSQA.contoso.com}

This command modifies the ServicePrincipalNames property for the AccessTSQA MSA. The command uses the Get-ADServiceAccount cmdlet to get the AccessTSQA MSA, and then passes the AccessTSQA MSA to the current cmdlet by using the pipeline operator.

Example 6: Set an MSA from a local instance

PS C:\> $ServiceAccount = Get-ADServiceAccount -Identity "AccessTSQA"
PS C:\> $ServiceAccount.ServicePrincipalNames = @{Add=ACCESSAPP/TSQA.contoso.com}
PS C:\> Set-ADServiceAccount -Instance $ServiceAccount

This example modifies the ServicePrincipalNames property for the AccessTSQA MSA. The example modifies a local instance of the AccessTSQA MSA, and then specifies the Instance parameter for the current cmdlet as the local instance.

Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-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 once a default value can be determined, no further rules are evaluated.

In Active Directory Domain Services (AD DS) environments, a default value for Partition is 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 is 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 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 Partition parameter will not take any default value.
