Printing from Lion to Cups 1.5.0

[hans peter verne]

I installed cups 1.5.0 from src on a server (RedHat 5.7), and set up queues.
We want basic authentication (username/password, no kerberos).  I set
LogLevel debug in cupsd.conf .

Then, I try to set up a few queues on a Mac OS X 10.7 "Lion" (build ver. 11A511).  When I try to print, the printer icon starts to jump
around, and I can click on it open the queue window, and click "Resume".
I can now enter a username/password  (Actually, I have to run
lpadmin -p queue -o auth-info-required=username,password
in a shell for this to work).  Nevertheless, the job drops back to
"on hold (Authentication required)", and on the server I see this
in the error log:

I assume the first "No authentication data provided" is legit, as this
is before I type my username/password, but the second time (16s later)
this should work...   Any suggestions as to why it doesn't?
