Talk:Linux Winbind Setup
for sudo on arch, I also needed to modify /etc/pam.d/sudo
arch pam setup
In arch, the pam config listed here is a little outdated.
The jist of it, replace ... required pam_unix.so ... with ... sufficient pam_unix.so ... and add the ... required pam_winbind.so ... after each pam_unix line.
This is also required: https://wiki.archlinux.org/index.php/Active_Directory_Integration#pam_winbind.conf
