we use the Update AD-User Action to update attributes of a user - also the manager - i can't solve the issue to clear the manager attribute. Empty field as mapping doesn't work. Any suggestions for clear a Manager field AD attribute via Nintex Workflow?
I found this information:
AD does not allow you to assign either blank strings or nulls to any attribute. Technically, you must clear the attribute, after which the attribute is not saved for that user in AD. When you pass $Null to a parameter of Set-ADUser, under the covers PowerShell must invoke a Clear method.
