Tests a managed service account from a computer.


    [-AuthType <ADAuthType>]
    [-Identity] <ADServiceAccount>


The Test-ADServiceAccount cmdlet tests a managed service account (MSA) from a local computer.

the Identity parameter specifies the Active Directory MSA account to test. You can identify a MSA by its distinguished name (DN), GUID, security identifier (SID), or Security Account Manager (SAM) account name. You can also set the parameter to a MSA object variable, such as $<localMSA> or pass a MSA object through the pipeline to the Identity parameter. For example, you can use the Get-ADServiceAccount to get a MSA object and then pass that object through the pipeline to the Test-ADServiceAccount cmdlet.


Example 1: Test an MSA

PS C:\> Test-ADServiceAccount -Identity MSA1

This command tests the specified service account, MSA1, from the local computer. The test indicates whether the account is ready for use, which means it can be authenticated and that it can access the domain using its current credentials.
