Well, off the bat seeing this in the RADIUS module as soon as I try to access the Guacamole logon page:
```

I seem to recall having this issue before with the RADIUS module - seems like one of the `jradius` dependencies pulls in a different version of SLF4J if you don't specify the `provided` tag for that dependency in the `pom.xml` file.
