[Samba] Samba 3.0.2 uid filtering

[Ric Tibbetts]

All;
I'm running Samba 3.0.2 w/winbind on an LDAP server (for various reasons).
However, our NT PDC managers input the user IDs oddly. They come out looking like:

-rwxr--r--   1 NORTHGRUM+tibberi 100000   45766615 Feb 17 10:05 Fonts.zip

Is there an (easy) way to filter those, to get rid of the "NORTHGRUM+"?
Our NT admins add that as a way of identifying the network the user is on.

Thanks!
