Thanks.  I did a little more poking around and it seems like I'm leaning
towards using winbind as my definitive authorization for this server and
removing NIS from the fileserver.  If I do this, I'll need to get LDAP up
and running to control the mapping of SID -> UID so my NT SIDs map to my NIS
UIDs for UNIX NFS clients that mount the volume(s).  I've seen several
descriptions of how to get the Samba side up (basically use the "idmap
backend" option in smb.conf), but I'm completely new to LDAP, and I haven't
found a simple description of how to set up an minimal LDAP server (probably
using OpenLDAP) on my linux box that would just contain the SID->UID

Does anyone have a simple example configuration for OpenLDAP that they would
like to share?  You can post, or email me directly at:  looper_man at yahoo.com

Thanks in advance,
