Description n_k_samal 2008-04-19 08:56:50 UTC 
Description of problem:
The root user generally works by logging as ordinary user. In cases of need the 
root user does a "su root" or enters the root password when asked by gui tool 
system-config-printer and carries out necessary configuration changes. Most of 
the time the system does not respond when the root user tries to use the 
graphical gui tool system-config-printer.

Version-Release number of selected component (if applicable):
Fedora-9-Beta-i386

How reproducible:
Log in as root and run the gui tool from system-config-printer from applications

Steps to Reproduce:
1.Log in as ordinary uses
2.Go to applications > printing.
3.Press enter
4.If no response for about 20 seconds log out and re-login again as non root 
user and repeat steps 2 and 3
5. If no response try step 4 once again.
6. After two /three/four trials the system asks to enter root password.
7. Now necessary changes can be made.
  
Actual results:
Most of the times no response.

Expected results:
The system should have asked the non root user to enter root password on the 
first time itself since he does not has the required privilages.

Additional info:
Full system profile is at http://www/smolt.org/show?/uuid=pub_85955a62-7804-
46c3-9010-eb5cf098549a.
No such problem was seen in F7. Every time the graphical GUI tools system-
config-printer was invoked by not root user, the system used to ask for root 
password. Once root password was entered necessary changes could be made.
Comment 1 Tim Waugh 2008-04-21 14:12:17 UTC 
I haven't been able to reproduce this.

Whta does 'rpm -q system-config-printer' say?
Comment 2 antonio montagnani 2008-05-09 08:03:27 UTC 
I have same problem:

If I start as root the graphical tool for printing everything seems o.k, but as
standard user I am not requested for password and I get a message stating:

CUPS server error
HTTP error: not connected
Comment 3 antonio montagnani 2008-05-09 08:04:50 UTC 
system-config-printer-0.7.82.2-4.fc9.i386

I forgot this piece of info
Comment 4 Tim Waugh 2008-05-09 08:20:22 UTC 
I'm a little confused: in the original report it seemed like the problem was
that system-config-printer wouldn't start when logged in as root, but in comment
#2 it looks like the problem only occurs when logged in as a *non-root* user.

When I try this here I don't see any problem at all.

Please attach your /etc/cups/cupsd.conf file.

Comment 6 Tim Waugh 2008-05-09 11:48:24 UTC 
Please try running 'system-config-printer' from the GNOME terminal window --
does that make any difference?  What output does it give?

I apologize for the Italian :-)

It was working fine!!! because sometimes I used to open this window to test if
Bugzilla Bug 439154: Cannot print on a Windows shared printer had been
solved!!!
Comment 9 Tim Waugh 2008-05-09 12:13:14 UTC 
When logged in as the non-root user, what output do these commands give?:

1. ls ~/.cups
2. lpstat -s
3. system-config-printer
Comment 10 antonio montagnani 2008-05-09 12:35:45 UTC

Comment 13 Tim Waugh 2008-05-09 13:35:12 UTC 
The exact circumstance this occurs is when a local queue exists that uses an
'smb://...' URI.
Comment 14 Will Woods 2008-05-09 21:29:12 UTC 
Note added to http://fedoraproject.org/wiki/Bugs/F9Common. Moving to F9Target.

Tim, is there a fix for this in the current s-c-printer build for F9 in koji?
Comment 15 Tim Waugh 2008-05-12 08:58:10 UTC 
Yes, system-config-printer-0.7.82.3-1.fc9 has the fix.
Comment 16 Bug Zapper 2008-05-14 09:42:30 UTC 
Changing version to '9' as part of upcoming Fedora 9 GA.
