Hello there,
What is the length of the login user names in AD? It seems to take no
more than 20 characters including the dot[firstname.lastname]. Any way
I can get around that limit? Thank you, T

I assume you mean the "pre-Windows 2000 logon name". The value for user (and
group) objects is limited to 20 characters. This is the NetBIOS name of the
object, so this is a limitation of NetBIOS. For computer objects the limit
is 15 characters. The sAMAccountName for computer objects is the NetBIOS
name plus a trailing "$", so the sAMAccountName of computer objects is
limited to 16 characters.
