samba - May 2004 - Samba & Groups

Admins,

I am working on an issue with Rational Clearcase with Samba as a PDC.  I 
am new to Samba and learning fast :)  Could anyone help me with finding 
information on how Samba uses group(s) functionality with Unix and NT?  I 
really am looking for information on how samba handles groups from the NT 
side.

Thank you and I appreciate you supporting my learning.
