Comment 1 Volker Lendecke 2005-09-16 04:22:39 UTC
Could you please recompile Samba with debugging symbols. Instead of ./configure
you might use ./configure.developer. And please upload all winbind log files.

If it's possible for you, running the -g compiled winbind under valgrind will
probably provide much more detailed information on what has failed.

You get valgrind from www.valgrind.org.                                        
                      
                                                                                
Please run it with the following options:                                       
                                                                                
valgrind --tool=memcheck --leak-check=yes -v --num-callers=20 \                 
--trace-children=yes --log-file=/tmp/smbd.vg winbindd -d 10 -i
   
and upload the resulting file.

Thanks,

Volker

Comment 4 Volker Lendecke 2005-09-16 08:56:54 UTC
Is it possible that you did not run winbind as root?

Volker
Comment 5 Fabian zur Heide 2005-09-17 07:10:28 UTC
Yes, I did run it as root.

Comment 6 Volker Lendecke 2005-09-17 09:23:09 UTC
The error message in the logfile poses a question:

Could not fetch our SID - did we join?

What is your configuration? Could you attach your smb.conf? Did you join the
domain you are member of? Or are you a domain controller?

Volker
Comment 7 Fabian zur Heide 2005-09-19 00:42:46 UTC
Here is the smb.conf:
I've added the two idmap lines in global. Since then the requests are handled
very quickly.

Regards, Fabian

security = server is not a domain member server configuration.
Please re-read the docs.  Thanks.
