samba - Apr 2005 - Windows Server 2003 SP1 Issues (3.0.15pre2)

Hi All,

I'm running into some issues accessing a Samba server that's in turn 
authenticating against a Win2k3-SP1 domain controller (security=ads).  I 
understand there were some known issues corrected in a patch, and I'm 
currently running 3.0.15pre2, which I understand includes that patch.

  (http://samba.org/~jerry/patches/post-3.0.13/winbindd_2k3sp1.patch)

All was working fine before the Win2k3 server was upgraded with the SP1 
service pack.  The `net ads join`, `wbinfo -t`, `wbinfo -u`, `wbinfo -p`, 
`getent passwd`, and `getent group` commands all still work fine, but 
users can't authenticate against the Samba box and view available shares.

For example, here's a local smbclient connection from the local console:

   [root@linux-test samba]# smbclient -L 192.168.0.52 -U polorx
   added interface ip=192.168.0.52 bcast=192.168.0.255 nmask=255.255.255.0
   Client started (version 3.0.15pre2).
   Connecting to 192.168.0.52 at port 445
   Password:

   SPNEGO login failed: Logon failure
   session setup failed: NT_STATUS_LOGON_FAILURE
   [root@linux-test samba]#

I have attached the Samba server's configuration file, and I can also 
provide detailed logs upon request.  Does anyone have any ideas on this?

Thanks, in advance, for any insights you can offer!
