samba - Nov 2003 - Samba3 and AD

Hi all,
 
I'm trying integrate my Redhat 7.3 machine with Win2000 server Active
Directory, such that users can logon to the Linux box using AD accounts.
I have successfully join the Linux box into the domain as a domain
member server, and current linux account users can access their Samba
share from their Windows machines. When I tried to configure winbind, I
was hit with a problem when trying to list domain users:
 
# wbinfo -u
Error looking up domain users
 
When I check /var/log/samba/log.winbindd, it kept saying improper format
of Kerberos config file
 
[2003/11/27 14:59:37, 1]
nsswitch/winbindd_util.c:add_trusted_domains(206)
  scanning trusted domain list

  Kinit failed: Improper format of Kerberos configuration file

Below is my global configuration for /etc/samba/smb.conf and
/etc/krb5.conf:
 
/etc/samba/smb.conf
[global]
 
# workgroup = NT-Domain-Name or Workgroup-Name
   workgroup = SMUSTF

   server string = Samba Server
