Tests a managed service account from a computer.

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 Accounts Manager (SAM) account name. You can also set the parameter to a MSA object variable, such as $ 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.
