How to rejoin a linux server to a linux domain

[Red Squirrel]

I recently did an update to samba on my DC which resulted in me having to rejoin all PCs to the domain. I noticed since then all my backups are failing on my linux servers. Mount.cifs wont work at all, just fails.

mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)

I'm guessing this has to do with the domain not properly authenticating. The password IS valid, and this worked before the domain incident.

Are you running mount.cifs as root? If not, was it setuid before and not now?

 

[Red Squirrel]

Yeah running it as root.

What does it say if you add --verbose?

Weird I could have sweared I posted but my post is not showing up.

This is what I get:

[root@borg ~]# /data/scripts/cron/cpdev_backup 
parsing options: user=root,pass=q1w2e3r4

mount.cifs kernel mount options unc=//cpdev\data,ver=1,user=root,pass=q1w2e3r4 
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
premature script termination due to mount failure

This is my code:

if ! mount.cifs //cpdev/data /mnt/cpdev/ --verbose -o user=root,pass="q1w2e3r4" ro
then
echo "premature script termination due to mount failure"
exit
