Powershell termination script to remove manager from direct reports

Question

Working on a powershell script for termination and I want it to remove the terminated user from the manager field of any users that currently have it.  I know I can't use the direct reports data as it doesn't link correctly.
Looking essentially for a script that would filter all users based on the manager field and then based on those filtered users, set the manager field to $null.
I have tried commands to the effect of
get-aduser -filter { manager -eq "<username of term'd user>"}
and also
get-aduser -ldapfilter '(manager=<username of term'd user>)'
But both commands come back blank even though I know there are users in AD with that manager.
I've searched the interwebs, but can't seem to find this specific item.
Any assistance would be greatly appreciated

Answer 1

Manager isn't one of the default properties returned by Get-ADUser, which is why you need to specify it.
What happens if you run this:
Get-ADUser -Filter "Manager -eq 'CN=Walter White,OU=Users,OU=*DECOM,OU=*GLOBAL,OU=*Furmanite,DC=fwwi,DC=net'"
I've never had an OU with a '*' in it, perhaps that's causing your problems.

Well, looks like you're right on the "*".  I moved Walt to the default User OU in AD and it worked:

Your original recommendation works when Walt is in the default Users OU as well.
