I am trying to add a specific user on a SharePoint Site. While searching for that user in Address book by"Name" say "User A", its showing the correct user. But when i add that user by clicking Ok, the user changes to say "User B". When searching the user by domain\username (for User A), it only shows two occurrences of "User B".
This issue does not occur when i try this on a different server hosted Site with same AD.
Also, i have tried both full and incremental import of user profiles in SSP.
Any help would be much appreciated.
