Hello,

I have samba 3.3.8 installed on CentOS 5.5 on a production server.

Winbind is filling up the logs with these messages:

If you enable debug level 10, do you get this just before each of
those messages?

Converting SID S-1-5-21-2106371596-187675891-3351287853
Yes. Here is a snippet:

We have been having problems when activating winbind daemon.

Could this error message be causing trouble?
I don't think so.  I'm not sure what would cause this, but the code
logs that message if the SID is not in the BUILTIN domain and is not
in your domain and is not a local user/group and is not a well known
SID (like "Everybody").

It looks like just a sanity check.  I have no idea what it has to do
with deadlocks, but perhaps someone familiar with the code could
comment.

The SID that appears in the logs is the domain SID:

[r...@phoenix samba]# net getdomainsid
SID for local machine PHOENIX is: S-1-5-21-2106371596-187675891-3351287853
SID for domain DF-CGU is: S-1-5-21-2106371596-187675891-3351287853

Attached is smb.conf globals section (shares removed).

Thanks in advance
