Active Directory

Hey, Cem.
I strongly suggest you implement Active Directory. Personally I like FileVista, but my company want Active Directory  file manager. Keep up the good product.

Hi Joe,
Actually, Active Directory is supported, ie. you define users with same names in FileVista (like domain\username) and then turn off FileVista's internal authentication.

Please see how to do it in the below thread:
