Does anyone know the max number of characters a username
can be in Active Directory. Currently it's 20 here with
Exchange, using User Manager. We have a SQL database that
holds usernames for login purposes and we're wondering if
it will need to grow the size of the column and database
in preparation for Active Directory.
Thanks
 
Active directory supports logon names up to 104 characters (although not
recommended - MS suggest no more than 64). Remember that SAM account names
are still restricted to a max of 20 characters and every SAM account in the
domain needs to be unique.

Regards

Paul
