[Samba] Question about SIDs RIDs UIDs and GIDs

[Rhys Goodwin]

Hi Guys,
Just a quick one...I use ldap backend for samba users and unix(PAM+NSS)
users. If I was creating a new user/group/computer manually do the RID and
UID/GID have to match up somehow or something?? I mean I've been reading
somewhere that that RID should be somethings like UID+2x1000 or something??
Algorithmicbase?? Whats this all about?
Am I making any sense?
 Cheers,
Rhys
