[Samba] Samba Core dump when using AD groups on the Linux File System??

[Mostro Mostro]

Hi all,

smbd -V:   Version 3.0.23d-19.2-1179-SUSE-SL10.2

I'm seeing a core dump in /var/log/messages when trying to access the
security tab from Windows when I have Active Directory users and groups
assigned to the Linux file system.

I can replicate this each time by doing the following.

Change the permissions on the Linux directory I have specified as a share in
smb.conf.

ls -ltr /dir/
drwxrwxrwx  2 root                  users                     4096
2007-03-10 09:17 shared

With these setting I can access the security tab from Windows without seeing
any errors in the messages log.

Permissions from the security tab show up as:

Everyone
root (Unix User\root)
users (Unix Group\users)

Now, I change permissions on the file system to:

 chown -R "DOMAIN\administrator" shared/ && chgrp -R "DOMAIN\domain users"
shared/

ls -ltr /dir/
drwxrwxrwx  2 DOMAIN\administrator DOMAIN\domain users  4096 2007-03-10
09:17 shared

Next, go back to access the security tab on the share while tailing the
messages log. I receive this:

The log below doesn't get created until I click on the security tab.

P.S. I'm really new to SAMBA as a domain member server and I don't want to
waste anyone's time with useless information. So, if there is more
information or further debugging needed before I post let me know...

Thanks in advance...
