samba - Mar 2004 - Winbind Kerberos Problem? - Getting Wrong User SID

I am having trouble getting users connected to shares after setting ACL
permissions on the share (removing the Everyone group and adding
specific users). I have no problem with wbinfo, getent, or net join
commands. I can also kinit a user and use smbclient -k to connect to
windows shares from the samba server. I have removed ncsd from the
system to make sure it can't run. BTW, the user can connect if the share
is access via the IP address of the samba server which forces the
authentication back to NTLM (?) rather than using kerberos.

Any help would be greatly appreciated. I cannot figure out where the
incorrect sid is coming from or why this is happening.

Thank you,
Steve Aden


Configuration:
Samba 3.0.2a on Fedora Core1 (exact same problem running Samba on RH9)
joined as a domain member.
Windows 2000 (Service Pack 4) ADS

Turning up the logging to 10, I see the following in the log:

[2004/03/11 14:14:50, 10] lib/util_seaccess.c:se_access_check(234)

[2004/03/11 14:14:50, 5] lib/util_seaccess.c:se_access_check(315)
  se_access_check: access (2) denied.

The problem here is that the user sid does not match the actual sid of
the user and displayed on the workstation the user is logged into. This
is verified with the Microsoft reskit command "whoami /all". Above the
user sid being checked ends with 21006. The actual sid ends with 1586.
The sid list for the share near the end actually contains the sid ending
in 1586, but obviously doesn't match the incorrect sid of the user.

wbinfo -s S-1-5-21-74637098-2648309090-xxxxxxxxxx-21006  "Could not
lookup sid"
wbinfo -s S-1-5-21-1202660629-1292428093-xxxxxxxxxx-512  DOMAIN_testgirl (This
is correct)

I notice some other strange things that may be related.
Running getent passwd | grep -i mysambaserver I get
"DOMAIN_HOST/mysambaserver:x:..."
Running getent passwd | grep -i mywindowsserver I get
"DOMAIN_MYWINDOWSSERVER$:x:..."

I don't know why these would be different. Joining the samba server to
ADS appears to append HOST/ to the name? Also my other computer names
have a $ at the end of the name. Also, most of the log files are being
created under their IP addresses, instead of the computer name.
