Kerberos conundrum in CUPS.

[peasthope@shaw.ca]

Folk,

This conundrum is in CUPS in Squeeze with LXDE.  The "server" 
is only my server at home used by me.  
 
Until this weekend, an attempt at an administrative task by a user 
on the Web interface would get a dialogue window.  After authentication 
as root, the task could be completed.

Now such an attempt gets this message.
"401 Unauthorized

Enter your username and password or the root username and 
password to access this page. If you are using Kerberos 
authentication, make sure you have a valid Kerberos ticket."

Given the absence of any dialogue for authentication, the message 
implies that Kerberos is present.  But aptitude doesn't show any 
package with "kerberos" in the name as being installed.

So what brought this and what solutions are available?  The firewall 
will prevent access from outside the home LAN and a trivial policy 
"allow anyone to print or administer without authentication" should 
suffice.  Is there any harm in replacing the cumbersome 
<Policy default> ... </Policy> and <Policy authenticated> ... </Policy> 
sections of /etc/cups/cupsd.conf with just "AuthType None"?

Thanks,                       ... Peter E.
