Hi all,


	We've recently upgraded our main production Samba server (Solaris
9) to 3.0.24 (compiled from source)


We're now getting a spate of problesm which look like:-

[2007/03/19 12:02:11, 3, pid=436] smbd/sesssetup.c:reply_sesssetup_and_X_spnego(691) NativeOS=[Windows 2002 Service Pack 2 2600] NativeLanMan=[Windows 2002 5.1] PrimaryDomain=[]
[2007/03/19 12:02:11, 3, pid=436] libsmb/ntlmssp.c:ntlmssp_server_auth(672) Got user=[] domain=[] workstation=[68S7C1J] len1=1 len2=0

the transaction then goes onwards to contact the DC (seemingly OKay) and
produces

[2007/03/19 12:02:16, 3, pid=436] auth/auth.c:check_ntlm_password(270) check_ntlm_password: guest authentication for user [] succeeded

Not really surprising that it's authenticated user '' as guest.  but not
helpful either.


I don't know for certain that this is the first event in the chain, I
only turned debugging up on one smbd process after the problem became
apparent.


It's not happening on all connections, nor to all users.



We're looking at generating a level 10 log of the issue, but it's time
for lunch just now and I'm starving.

I couldn't find anything like this elsewhere.
