[Samba] Problem with winbind

[zottmann]

Hi! 

Since we migrated to Fedora Core 3 our Linux box where we run Squid, wich, 
in turn, uses Samba´s winbind to do ntlm authentication, we are experiencing 
a weird behavior in this authentication, wich I think relates to winbind. 

We are running samba-3.0.8-0.pre1.3, and Squid is randomly displaying an 
authentication windows to the user. Reading the winbindd.log, I have found 
the following messages: 

cli_nt_session_open: cli_nt_create failed on pipe \NETLOGON to machine <OUR 
SERVER>.  Error was NT_STATUS_PIPE_NOT_AVAILABLE 
cli_nt_create failed to \PIPE\NETLOGON machine <OUR SERVER>. Error was 
NT_STATUS_PIPE_NOT_AVAILABLE 

I have tested wbinfo -t, wbinfo -a user%password, wbinfo -u, wbinfo -g, and 
it all worked ok. 

Does anybody know what may be going wrong? 

Thanks in Advance, 
Carlos.
