[cups.general] MacOS cups 1.4.1 client keep trying to access server configuration

[Guillaume Rousse]

Hello.

Since one of my users switched to MacOS Snow Leopard, he has troubles 
accessing the shared printers hosted by the print server.

I tried the following configurations:
- setting client.conf to directly access the shared print server
- setting client.conf to access local cups server, and setting the local 
cups server to poll the shared print server
- setting client to access local cups server, and configuring the local 
cups server to receive printer notifications with cups 'protocol' (not 
available on every networks)

NB: the print server is not on the same network as users, neither the 
printers themselves, hence this complexity.

In all cases, the command-line level seems to works fine (lpstat -a show 
available printers), but not the graphical interface level: printer 
properties panel (approximate naming, I'm not a macos user myself) seems 
to freeze regulary, and some debug logs refer to authentication attempts 
occuring.

On server side, it seems the client keeps sending requests to the server 
for its configuration, and fails obviously:
segur.msr-inria.inria.fr - - [15/Sep/2009:18:15:18 +0200] "GET 
/admin/conf/cupsd.conf HTTP/1.1" 401 0 - -

So, what is this new behaviour ? Does the macos client assume the print 
server is always the local one, for which the user is supposed to have 
admin privileges ?
