I'm having the toughest time getting this to work... I have a windows 2000
domain and i'm in the process of adding a Samba fileserver... All of the
setup guides i have seen point me in the right direction, but fail to
provide assistance for my single problem...

basically i've figured out that if i have security = share. I can run the
gentent passwd command and see the domain accounts in the list! thats
great!!! but if i have security = ads, then the users disappear when i run
the command. and i have to have a matching user account in linux to access
the shares at all, and thats just plain silly!!!

I do see one error in the log.winbindd but i am unable to get past it.

  scanning trusted domain list

I did kinit, net ads join, and can test via wbinfo & smbclient... all is
well!!! just no getent passwd or groups

I also dont see the kerberos error when winbindd starts in share mode...

Where can I look? HELP!!!

I've given my smb.conf, krb5.conf, and ldap.conf... The nsswitch.conf is
set and so are the PAM's
