[Samba] Samba ADS Winbind unable to join SuSe 9.1

Hi all,

We are trying to add SuSe 9.1 file server to Windows Domain. Here is
our configuration.

      Windows 2000 Active Directory
       SuSe 9.1 with Samba 3.0.8
       
  When I try to add Linux file server to windows domain using net
command, net command dies with segment fault message. While starting
winbind process, it dies with segment fault error message.

Here is my configuration files and error message on this problem.

smb.conf:
