Nick Couchman commented on GUACAMOLE-355:
-----------------------------------------
So, if I do GuacamoleInvalidCredentialsException, the user is redirected back
to the usual login page, but no error message (due to the redirect). If I do
GuacamoleInsufficientCredentialsException, the user is brought to a
not-quite-so-nice-looking login page (which I'm sure could be easily brushed
up), but is actually given the error message. The Invalid exception sounds
more correct; the Insufficient exception behaves more correctly. Thoughts on
which way to go?
> CAS Module Missing Error Handling
> ---------------------------------

> Key: GUACAMOLE-355
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-355
> Project: Guacamole
> Issue Type: Bug
> Components: guacamole-auth-cas
> Affects Versions: 0.9.13-incubating
> Reporter: Nick Couchman
> Assignee: Nick Couchman
> Attachments: castrace.txt

>
> As reported by Kaushnik on the dev mailing list, attempting to use the
> guacamole-auth-cas module with an incorrect CAS authentication endpoint
> results in very generic and not very useful 500 Internal Server errors rather
> than meaningful messages that point the user in the right direction for
> correcting the error. Need to see if the CAS framework has any built-in
> error checking facilities and try to leverage those, or at least throw some
> more meaningful Guacamole errors when we run into problems.
