I'm running Suse 10 and have domain authentication working correctly via samba+winbind+kerberos. I can log on via ssh as administrator of the domain or locally via console. I've added the following line to sudoers:
but I still can't "sudo su". I get the message:
administrator ALL=(ALL) ALL
sudo: pam_authenticate: User not known to the underlying authentication module
I've checked the pam for sudo and it references the four common-* files which ssh and login also use so this should just work.
This all works on another gentoo machine.
What have I missed?
Did you check /etc/pam.d/sudo file?
