bug#63198: cups-service-type uses PAM-enabled 'cups' by default which prevents authentication

[muradm]

This change broke cups for me like this:

cups-minimal does not include ippfind utility.

Normally, user whishing to use cups, should be in lp group, isn't 
it?
Maybe that was your original issue?
