Hi Bryan, I don't see why the gateway feature would be required for the use case you describe. If Canvas is to allow both CAS and a local-to-Canvas-account login, I'd have expected this to be accomplished by customizing the *Canvas* not-yet-authenticated experience to offer links for both CAS and local-to-Canvas login.
Cf. e.g. Yale's Sakai, which supports both CAS and local-to-Sakai login: https://classesv2.yale.edu/portal/ Note the Yale CAS Login and the Non-Yale Login links at upper right. No gateway feature usage required. Gateway comes into the picture if, beyond supporting both CAS and non-CAS login, Canvas is looking to detect an already established CAS single sign-on session and skip presenting the invitation to login, jumping straight to the logged in experience when possible thanks to an already-established CAS single sign-on session. I'd suggest that's possibly a better experience worth getting to, but not a nuance to address before eating basic CAS and non-CAS login working. There's no issue with the gateway feature in the Yale CAS client that I know of. That client library works just fine until/unless you need features it doesn't support. Hope the conference call goes well. Kind regards, Andrew On Jan 25, 2012, at 11:36 AM, Bryan E. Wooten wrote: > Hi all, > > We have deployed Canvas as our LMS and it is CASified.
