[Samba] Change print job priority

[Necos Secon]

I believe the problem is that only users in the sys group can modify job 
priorities. So, this includes root. If your user is not part of an admin 
group (done with net groupmap or using /etc/group), then I suspect that you 
will get access denied errors. All members of "Domain Admins" have this 
right, as they are directly mapped to root.

Hope that helps.
