Bug#1006468: cups: misleading documentation regarding root login credentials

[Celejar <celejar@gmail.com>]

Package: cups
Version: 2.4.1op1-1
Severity: normal

Hello,

On a fresh CUPS install, I logged into the web interface as root to add
a printer, and was denied with a 401 Forbidden error. The problem seems
to be that root is not a member of a group in @SYSTEM (which by default
only includes lpadmin). I understand that Debian has decided that this
is not a bug:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=616718

but Debian's documentation seems quite misleading and inconsistent on
this point.

README.Debian states:

'Administration' is where you need to be to set up a local print queue.
At some point you will be required to authenticate. A User Name of 'root'
and root's password is always acceptable. Any other user must be a member
of the lpadmin group.

This clearly indicates that root does *not* need to be a member of the
lpadmin group.

OTOH, 'man cupsd.conf' is more accurate:

Note: The 'root'  user  is  not special and must be granted privileges
like any other user account.

I suggest that the language of the README be modified to resemble that
of the man page.
