Subject [jira] [Commented] (GUACAMOLE-355) CAS Module Missing Error Handling
Date Thu, 10 Aug 2017 13:23:02 GMT


Nick Couchman commented on GUACAMOLE-355:

Sorry, no insult meant there...just continuing a series of bad puns...

Anyway, I was able to catch the exception and throw a GuacamoleInvalidCredentialsException,
which results in a redirect to the Guacamole login page and a prompt for username/password.
 At the moment I cannot get this to actually display the error message, though - not sure
why it just gives the blank login page and no error.  Anyway, if I can get the error message
to show up I think this will take care of this issue.

> 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.
