Yes, everybody has (and uses)a unique login name.
Furthermore they are members of only two groups: Domain
Users, and a group specific to their location.
Their data is separate and they have access only to their
data. They also have no need whatsoever to print from a
printer at their location to a printer at another
location (That right is reserved only for
Administrators). The only common denominator is
membership to the Domain Users group which is NOT on the
ACL for ANY printer, yet they can still print to any
printer....
