Samba Team, could you please advise if I have broken security by making
the following changes.....Thanks.........TJ
This may or may not be applicable to your case but take a look at the
following I just did on my Mandrake box:

> [tim@localhost tim]$ wbinfo -a tim%secret
> plaintext password authentication succeeded
> challenge/response password authentication failed
> error code was NT_STATUS_ACCESS_DENIED (0xc0000022)
> error messsage was: winbind client not authorized to use winbindd_pam_auth_crap. Ensure permissions on /var/cache/samba/winbindd_privileged are set correctly.

Once this worked I changed the group ownership to "Domain Admins". Then I tried again, no root this time, and it seceded!

> [root@localhost tim]# chgrp "Domain Admins" /var/cache/samba/winbindd_privileged/

I hope this helps.....TJ
