PolicyKit has arrived through GNOME to Ubuntu 8.04.
As I am a pointer-only user, I do all my typing with an onscreen keyboard; on Ubuntu it is mostly the onscreen keyboard named onboard.
Unfortunately, the onscreen keyboard is not able to enter anything into the Authentification dialog. This is a major problem as the people that do their input only with the pointer (disabled people, tabletpc users,...) are not able to perform any administrative task that involves authentification through policykit. (Or is it policykit-gnome?)
You can find the corresponding bug that I filed against policykit in Ubuntu at the following address:
And here is a thread that I started on the gnome-accessibility-list about the problem:
Hoping that somebody will be able to provide a solution.
This bug should be filed in the GNOME bug tracker, under the PolicyKit-gnome product.
Thanks for pointing me to the right product; here is the url to the bug that I just filed in GNOME against policykit-gnome:
This is fixed in policykit-gnome now. There is a GConf key to set whether the dialog should grab the keyboard. Marking as fixed.
