I can send you my smb.conf for use on linux and 8 smal scripts I wrote to make the SAMBA PDC seem nearly identiucal to a NT Domain. Means no AD though (whoopty who care)
I also have a good reference I am re-writing to be more "distro neutral"
I am || this far away from having LDAP in place for golbal authentication... and then I can replicate away on everything.
The only things I am not doing(yet) *IS* ldap and NTLMv2 as I have an OLD win95 box that will NOT use it, even though it can.
There are TONS TONS of things you can do. Right now I have cups as my print backend, and I am just starting to load up the drivers for all the printers.
I have some basic policies in place (some user and a few group) allowing me to control a few things. Roaming Profiles work great. I can use svrmgr.exe to manage the domain now (cept a few thing) I can add users and they will get UNIX account (if I want, which I do) and they will be the same passwd. I can add groups with specific SID. I have a software depot share, I can add users to groups (and be reflected in unix and samba) and remove them as well. I can establish domain trusts, workstation accounts(to join the domain) reset passwords remotely on workstations using swat, I also could if I wanted to have samba control the dynamicDNS updates. There are more things that I can't even begin to think of samba is now doing.
Just make sure you start with 3.0.4 or later. Trust me, I just spent the entire afternoon rebuilding an upgrade gone sour from 3.0.2a to 3.0.4 because of the recent GDMFAHBSSM$ using QUALITY TESTING they use. "Hey! It builds! SHIP IT!"
Twas a hung process that I didn't catch soon enough. Corrupting nearly all of the tdbs. The hung process was during a logrotate event. SUXXORZ. But SAMBA did still run, just after about 4-6 hours it would stop allowing NEW domain logins, but would still allow share mapping (which was the workaround)
Enough... SAMBA is plenty light weight especially with LDAP and no winbind being needed (winbind does the external AD or domain authentication and automagic homedir creation etc...)
Will be putting a neutered version of my smb.conf up for perusal. Sometime soon.
