-------------- notes in an older ticket #130 (Closed) -------------

Authentication was worked on by Ankita a couple of years ago, and her approach turns out to the spot on. Shibboleth is the go-to authentication platform that's being used around the world, and needs to be fully integrated. Right now, there is shibboleth code in the master branch, but it's turned off by default.

I have not tested it, but I know that it needed some configuration work done (to be a trusted endpoint mostly) before it'll work.
