samba - Jul 2008 - Local GID conflicted with domain GID. Samba can't connect to shares

Hey All,

RedHat 9.0
samba-3.0.10-1*

*
I was attempting to allow several domain users the ability to log into 
my domain controller with their logins. Because the server had no local 
group set up for the users, I created them with the groupadd utility.  
About 10 minutes later I got a call from my users telling me they 
couldn't access their network shares because the drives hadn't been 
mapped.  I checked some things out, and sure enough the GID of one of 
the new local users conflicted with the domain group 'nobody'.

I'm watching the logs and i am seeing the following errors for all of 
our shares that people are trying to access on the domain controller:

Jul  1 11:05:36 lp-pdc1 smbd[1998]: [2008/07/01 11:05:36, 0] 
smbd/service.c:make_connection_snum(620)
Jul  1 11:05:36 lp-pdc1 smbd[1998]:   '/home/public' does not exist or 
is not a directory, when connecting to [public]


I have since removed the local groups that I added, thinking that this 
would fix the problem. It did not.

The directory exists and the permissions are as such:

drwxrwxrwx    4 root     nobody       4.0K Oct 22  2007 public


Any advice as to what I can do to salvage this? I have restarted samba, 
and the server but this has not fixed it.

I know my OS and samba are extremely out of date. They are like the 
because I do not want to wreck anything, like I just did...

Thanks,
Adam

Also,

This error just showed up in /var/log/messages

Jul  1 11:31:51 lp-pdc1 smbd[2305]: [2008/07/01 11:31:51, 0] 
rpc_server/srv_util.c:get_alias_user_groups(206)
Jul  1 11:31:51 lp-pdc1 smbd[2305]:   get_alias_user_groups: gid of user 
nobody doesn't exist. Check your /etc/passwd and /etc/group files

The user does exist

# grep nobody /etc/passwd
nobody:x:99:99:Nobody:/:/sbin/nologin

# grep nobody /etc/group
nobody:x:99:


The GID of the domain account is  2004.   Should the local GID match the 
domain account?  I don't think that it has ever matched before and it 
was working fine
