Binary package hint: policykit-1

I was trying to enter the connection window in system administration and it asked me several times to enter my password.

So is this bug a big one or is this one not really affecting the system?

[Corey (corey-osgood)]

As far as usability, I didn't notice anything different, but then again, all this system does is share a few hard drives, and occasionally I use firefox to browse the web. As far as security, I don't know, it doesn't matter to me since it's only available to the internal network, but it may to someone running it as e.g. a web server.

While changing proxy settings I have to enter twice the password, once for:
the proxy setting and once more for Gconf.

[Pedro Villavicencio (pedro)]

This is fixed already on 11.04 and 11.10 , marking the development task as fixed, sadly the fix was due to the port to GDbus so not sure how easy would be to fix this on Lucid without backporting the whole package... Leaving that task open though. thanks all.

Eol is very close now; time to use a newer release
