I was trying to get a user with EnsureUser to make sure that if the user doesn't exists on the site collection, it is added right away.

 Write-Host  "LoginName" $usernameau #this prints mydomain/username

         try {
           $userAuthor =  $spwebout.EnsureUser($usernameau) # getUserOut($usernameau)

        } catch   { 

        write-host $_.Exception 

Unfortunately I get the following exception:

System.Management.Automation.MethodInvocationException: Exception calling "EnsureUser" with "1" argument(s): "The specified user  could not be found." ---> Microsoft.SharePoint.SPException: T
he specified user  could not be found.
   at Microsoft.SharePoint.SPWeb.EnsureUser(String logonName)
   at CallSite.Target(Closure , CallSite , Object , Object )
   --- End of inner exception stack trace ---

   at System.Management.Automation.Interpreter.EnterTryCatchFinallyInstruction.Run(InterpretedFrame frame)
   at System.Management.Automation.Interpreter.EnterTryCatchFinallyInstruction.Run(InterpretedFrame frame)

What could be the problem? I am sure the user exists on AD.

EDIT: I have to look better into it but I've found out is that the user that gives me the problem is not enabled in AD.

  • do you call it with or without domain name? ex: testdomain\user ? or do you maybe even have claims authentification?

Found this solution in another thread...

$wApp = Get-SPWebApplication "http://nacho.sharepoint.taco"

In my case, my people picker must have defaulted to the domain I was testing in, not the domain I was try to add users from. My Profile Store is configured to pull from two domain (Test and Prod).
