On the Centrify Access Manager, when we search for the userid, the Centrify Access Manager is not found.
But when we add the userid in the system, it mentioned that the userid is duplicated. It seems that the userid has been cached and orphaned somewhere in Centrify.

Step 1: To find out duplicated users / objects, you may use Analyze feature in Access Manager. See Pix 1

Step 2: Analyse Results

You will notice

– Duplicate users in zones
– Orphan zone data objects and invalid data links

Step 3: Right-Clicked to fix the isses

You should be able to add the user.
