samba driving me nuts!

I hope someone out there can help me. I am trying to
get samba 2.2.1a (package from suse 7.3 sparc) working
on my SS20 (Linux 2.2.20-SMP). I'm just trying to map
win2k users to corresponding linux users (same logins,
passwords).

Samba is kicking my ass and I'm stuck...

Help!

---  Here's the problem: ---

Samba tries to change GIDs, can't, and panics. What's
weird is that samba can't change to GID 100, which is
valid and exists. This happens whether I use local
smbclient to connect or a remote win2k machine. Here
is the log:
(/var/log/samba/log.smbd)

[2002/09/20 23:56:11, 0] lib/util_sec.c:assert_gid(97)
  Failed to set gid privileges to (-1,100) now set to
(0,0) uid=(0,0)
[2002/09/20 23:56:11, 0] lib/util.c:smb_panic(1101)
  PANIC: failed to set gid

I've seen literally 100's of postings and
non-solutions out there, so if you have overcome this
with the same setup (kernel/samba version) please let
me know how!

------------

Things I've tried/already done:

- added users using smbpasswd
- turned on encrypted passwords in samba
- created a guest account for nobody with a valid GID
- added guest account in linux with smbpasswd
(necessary?)
- tried connecting locally via smbclient. trace
follows:

larry:/home/brad # smbclient -L larry -U brad
added interface ip=192.168.0.10 bcast=192.168.0.255
nmask=255.255.255.0
Password:
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 2.2.1a]
tree connect failed: code 0

Here is my smb.conf:
