JASIG CAS for osTicket
Update 2015-06-03: I have moved this plugin to its own project. The post below has been updated to reflect this.
Back when I was working at RPI I had setup a ticketing system to handle the volume of support related requests that were coming in via e-mail. I turned to osTicket but their authentication system has always been a bit.. err.. not user friendly. Given that many college campuses, including my own, utilize CAS I figured it was time to get that hacked into osTicket. Thankfully osTicket has built a plugin system that is fairly easy to use, albeit undocumented.
I wrote a nice PR for the support to go in but given that there has been radio silence since proposing it, I have decided to document how to include it on your own instance.
- CAS extended attributes for user name and e-mail addresses.
- Optionally appending a suffix to user names to allow mapping to e-mail addresses.
- Login for both agents and clients (can be toggled for neither, either, or both).
- Certificate validation (can be disabled for testing).
- Auto creates clients if not already in osTicket.
