We use long passwords (ie 37 characters in length) and when trying to
authenticate via the CUPS web interface, the authentication fails. We
think it fails due to the length of the password and that the web
interface either can't handle the length or truncates before passing to
PAM. On our system, it looks as if CUPS is relying on PAM. On our
system, SSH relies on PAM too and they are both tied into the
system-auth module so this makes me think it's not PAM but the CUPS
web interface that's jacked due to the fact that we have no problems
authenticating via SSH. Here's some info.

We would like to keep our passphrase passwords so any ideas or help
will be appreciated.
