CAS Authentication in CI3

Hello,

I need a CAS (https://en.wikipedia.org/wiki/Central_Au...on_Service) authentication library for CI3. In CI2 we successfully use the phpCAS and this library:

But it no longer works in CI3 due to how the sessions work in CI3.

Using CAS is mandatory, we cannot use any other auth library such as Ion, etc. Anybody here successfully using CAS single sign-on with CI3 framework?

Thanks.
