I understand that CAS uses Forms Authentication and MVC 5 has now moved to OWIN. I've done some research and have found that there are a few people trying to implement this- https://groups.google.com/forum/#!msg/jasig-cas-dev/vPqa5X6aYew/FwciRjilbgEJ, and I have downloaded and included the files from Will Dean's Git repository- https://github.com/willdean/owin-cas.
My question is, how do I configure this to work with my CAS server? I have changed some login url variables but have had no luck.
We've a custom CAS implementation in our organization and Will Dean's project worked for me ...
Take a look at Startup.Auth.cs and configure properly casOptions.CasServerUrlBase.
ex: casOptions.CasServerUrlBase = "https://cas.contoso.com";
And don't put trailing / at url end :)
Maybe you need to implement your own CasAuthenticationProvider in order to customize it for your CAS environment, but I would first try to debug the authentication process to rule out things like wrong magic strings ... and use Fiddler to intercept request and responses!
