Get Guacamole working with CAS for SAML Authentication

I'd like to use F5 APM with Guacamole, and I think the easiest way to do that would be by doing SAML authentication using CAS. We're using F5 APM 13.1.0 and I can supply you with keys to get this working. I'd like to use the latest version of Guacamole and CAS which is Guacamole 0.9.14 and CAS is 5.3. As part of the project, you'll be required to provide me with the Maven Files that are a part of the build process for Guacamole and Cas and set it up in our environment by running the build process from scratch on a Linux server that's provided to you (or two if you find you need a different one for Guacamole and for CAS). We're probably only going to be using the SSH functionality (at least to start) and I have a list of usernames that will be using the SSH functionality if it's required. Or if you could suggest a better way of integrating F5 APM with Guacamole without the user needing to type in their credentials a second time to log in to, please let me know how we could do that and I'll look at it as well.
