Problem with GID being set to UID for Samba 2.2.2

I wonder if this is at all similar to the problem I have been having. Ever
since I changed a Linux user name by hand-editing /etc/passwd, /etc/shadow
and smbpasswd, my Samba install has been unable to resolve user names in the
list it provides to a Windows 2000 client when that client is changing
access permissions on one of its directories to RID (unless that user has
logged on to that machine before).
This has stayed a problem through an upgrade from 2.2.1a to 2.2.2. I have
been unable to figure it out and am considering completely nuking my Samba
installation and restarting from scratch (youch).
So keep me posted on your efforts; maybe your solution will also work for

Tony- thanks for the quick reply, but it probably doesn't solve the problem
(I will try the force group=users tonight at home but that still won't
explain where samba is getting nonexistent gid of 501 from.. 501 is not a
group in my /etc/group file!)

^^^^^ This is why the GID is being set. Thats what its
>to do :)
The GID should be set by Samba to 502 not 501, and it is being set to 501 in
samba according to the logs.

Yep understand & agree... but if you look at the "ls" output which I
attached, you can see that the uid:gid for "New Folder" created by pbabern
as a samba client has an owner:gid of pbabern:501 *NOT* 502!!! (i.e. group
501 is not recognised by the system, & as it is not in /etc/group it doesn't
print a group name!). Here is the "ls" again
drwxr-xr-x 2 pbabern 501 1024 Nov 4 18:05 Desktop
drwxr-xr-x 2 pbabern 501 1024 Nov 7 11:34 New Folder
drwxr-xr-x 2 pbabern user 1024 Nov 7 11:40 smb_prob
-rw-r--r-- 1 pbabern user 0 Nov 7 11:42 unix_touch
...and from the sbmd log file
smbd/uid.c:become_user(201) become_user uid=(0,501) gid=(0,501)
^^^ ^^^ should be 502 according to /etc/passwd
I created "New Folder" after I had deleted group 501, changed user pbabern
to be in primary group 502 (as per the /etc/passwd), and kicked xinetd in
the HUPs to force a daemon refresh (JIC).
unix_touch was created after "New Folder", by Linux root after su - pbabern,
then touch unix_touch. I don't understand where 501 is coming from, gid=502
is what I *want* it to do! Is there anything that samba does that would
cause it to cache gid=501 for user pbabern?
I can bodge my ownerships on the directories to make it work, but I'm trying
to understand where samba is getting gid=501 from, when group 501 has been
exterminated from the system. An interesting puzzle!
PS maybe it is the Jean Genie... the so-called "Bowie Effect"?
PPS wanted to do a better joke tying together disintegration of group 501,
the bugs bunny martian, spiders from mars, and 501 jeans but at this time of
the day I'm witted out
