Comment 8 for bug 292791

I just ran into this (horrible) problem today!
I haven't tried the proposed solution yet, but for the moment I want to detail how it came up in my experience.

- The system was up & running smoothly.
- I tried to add a printer though the CUPS web administration interface.
- When about to commit the modifications, CUPS asked for user and password. Username was already set to "root".
- I put my own password (not root's one), which CUPS refused.
- I went on typing the wrong password three times.
- I realized that maybe I should use my own login name, so i tried with my login and password.
- After that CUPS server crashed (didn't respond anymore)
- I tried to "sudo bash" in order to restart it
- sudo refused my password
- From then on, any attempt to log in with my username was refused, in the same way described in the original post
- Any attempt to use passwd to reset the password give "segmentation fault", either from root or from my user account.

Now I'm going to try editing the pam config files.

Please fix this bug. It's REALLY a pain!
