Is it possible to set a users memberOf property in Active Directory using Powershell

Question

I need to create a Powershell script that sets some user attributes in Active Directory.

I'm using the Set-AdUser command and passing in a user object as follows:

$user = Get-AdUser -Identity $userIdentity
$user.MemberOf = $dn_of_group
Set-ADUser -Instance $user

this returns an error of 'The adapter cannot set the value of property "MemberOf"'.

Is it possible to set the MemberOf property from powershell?

If so, what am I doing wrong?

Solution

You cannot modify the MemberOf property - you need to add the user to the group using the Add-ADGroupMember Cmdlet:

Add-ADGroupMember $dn_of_group $user
