[Samba] Running Samba 3 as PDC

[Irene Sakellarakis]

I am investigating options for using Samba 3.0.7.2.FC1 (Red Hat Fedora 
Core 1 basic installation, currently updating via yum) as a primary and 
only domain controller. We have a Windows user environment, and I'm 
trying to connect the user machines (XP fully patched as of this 
writing) to the samba domain but keep getting one of 2 errors: 1) 
"authentication failed", when I use the (smb) administrator account and 
password; 2) "user not known" when using the root account.

I've created the users (both unix and samba), mapped my groups, edited 
admin groups with the right entries). Frankly, I'm at a loss as to 
whether this is even feasible, realistically.

I've searched the various groups online but any reference I find to this 
type of setup is with pre-W2k clients and Samba 2.* versions. All the 
discussions I've found pertaining to 3.0 and W2k/XP are only documenting 
existing problems similar to mine with no responses to those threads.

Is it possible (at this point "advisable" has been thrown out the window 
by higher-ups) to get this functioning as a complete replacement to a 
Windows200* server environment? The official HowTo seems to hint at it, 
but I find little or no actual instruction on the matter.

Thanks much, in advance,
Irene
