0.8.3 is quite old at this point - it was released almost 4 years ago.
Though not the source of your issue, if possible, I recommend instead using
the latest release:

There have been quite a few improvements since the days of 0.8.3.

I have:

Why are you defining a user for Tomcat?

Your <authorize>...</authorize> section here is commented-out (see the
"<!--" at the beginning). You will need to remove the "<!--" and "-->"
surrounding that section for it to be actually read. See:

This is likely why you are unable to log in.

Lacking a VNC server running on the port defined within your Guacamole
connection would prevent the connection itself from being established once
you've logged in, but would not prevent you from logging in in the first
