We got our Sharepoint synchronized with Active Directory account names. So, the authentication goes through AD.

The question is, how to see these account names in Sharepoint? How to manage it as from Sharepoint side?

To be specific, one user in our system has several account names. Somehow, while using the services, current user account jumps from one to another. Does someone had such experience? How and where to admin this? How system decides which account it should take?

Any comments will be appreciated. thanks

UPDATE: Thanks to All, but my problems is not resolved. Actually I've found recently that account change happens while jumping from subsite to root site, and vice-versa. The OK account happens on subsite. The NOT OK account happens on a root site. "Not OK" account is not present in AD at all.

In hidden list suggested here there's only one OK account. I can't figure out where does it take old account name and why it jumps.

Any ideas/suggestions?
