Hi Guys, I have been running Linux for about 4 years now and currently have setup master controller in a Samba config (security=share) under Ubuntu, moved the DNSMasq off to a Pi box, setting up a DMZ with Apache+ and run a number of laptops with linuxmint and windows for the kids. I came across an issue with uid:gid on the server indicating Nemo does not pick up file ownership from the Dataserver properly and overlays it with local user information all of which has lead me to wanting to use an AD of sorts. The short of it is can you use Samba setup to run as a PDC for single point of user authentication?? ... understand that all Linux systems will need at least a primary user say 'admin' ... wish to setup the rest of the users in a single repository that can be auth from any laptop or PC Appreciate any assistance you can provide to make this happen. -- Thank you *Douglas Haig* Phone: 02) 6931-6853 Mobile: 0435-912861
