I did see an issue, at one point, where the RADIUS module needed to be
loaded before other modules in order to work.  I don't remember the
specific circumstances, but it seems like if authentication failed for a
user in one of the previous modules the RADIUS module would not even been
evaluated.  I don't know if this is a bug that should be addressed or just
an artifact of how the module stacking works with RADIUS, but, if you run
into issues with this, you might try renaming the RADIUS authentication
module and reloading Guacamole Client (Tomcat) so that it loads the RADIUS
module, first.  In my case, I just put a 0 in front of radius -
guacamole-auth-0-radius.jar - to force it to authenticate with that
extension before the others.
