    I am running the command to update the manager field of a user:

    Get-ADUser -identity sam | Select-Object -ExpandProperty  samaccountname | Set-ADUser -identity $_ -Manager 'James'

    However I am getting the error:

    Set-ADUser : Cannot validate argument on parameter 'Identity'. The argument is null. Provide a valid value for the 
    argument, and then try running the command again.

    How can I get Set-ADUser to except pipeline input?

    Simplest way, -identity aduser object gets passed over the pipe by value:

    Get-ADUser sam | Set-ADUser -Manager James

    You could do it this way if you want.  $_ must be inside a script block.


    Get-ADUser -identity sam | Select-Object -ExpandProperty samaccountname |
       foreach-object { Set-ADUser -identity $_ -Manager 'James' }

    or even this, since -identity accepts pipeline input, you can use a script block with it:

    Get-ADUser -identity sam | Select-Object -ExpandProperty samaccountname | 
      Set-ADUser -identity { $_ } -Manager 'James'

    Get-ADUser -identity sam | 
  Set-ADUser -Manager (Get-ADUser -identity <<managerSamAccount>>)
    No need to use ExpandProperty to get samAccountName. Manager property expects an ADUser object, so you need to use Get-ADUser to get the manager's object

    Actually, you don't need to select anything from the first Get-ADUser. Just piping Get-ADUser to SetADUser will identify the user.

    Edit: And -Manager "James" will work if "James" is the sAMAccountName of the manager.

    No need to use "Identity" here.

    Still does not work. With or without the -identity parameter. Getting the below error:

    Set-ADUser : Cannot validate argument on parameter 'Identity'. The argument is null. Provide a valid value for the argument, and then try running the command again.
    At line:1 char:37
    + Get-ADUser sam| Set-ADUser $_ -Manager( Get-ADUser James)

    As noted above you cannot use both the pipeline and the identity.  The pipeline variable only works when using it inside of a CmdLet and not as a parameter of a pipeline command.

    help pipeline

    When in doubt always start by reading the help for the commands you are trying to use.

    help Get-AdUser -full
    help Set-AdUser -full

    Read everything very carefully.  If you are still confused it means you need to start with a PowerShell tutorial in order to understand how this tool works.

    Microsoft Virtual Academy - Getting Started with Microsoft PowerShell

    After you have learned basic PowerShell this will all be less confusing.

    A simple demonstration of how a pipeline works.

    We create a CSV with only the samname of a few users then import it into the pipeline to a new command:

     get-aduser -Filter * -ResultSetSize 5 | select SamAccountName | Export-Csv users.csv -NoType
 import-Csv users.csv | Get-ADPrincipalGroupMembership

    Try it to see how it works.

    Hi,

    Thanks for your question.

    Get-ADUser sam| Set-ADUser  -Manager ( Get-ADUser James)

    You need to learn more about the pipeline from Jrv's links.

    Best Regards,

    Lee

    Just do it.
