SSO on Roller 5.1.1

Hi,

We’re upgrading our old installation of Roller 4.0 to 5.1.1. 

Our old setup uses acegi-based SSO to plug into the rest of our website’s authentication/permissions system.  We see that Roller 5 no longer uses acegi, and we cannot find anything about current “best practices” for setting up SSO on Roller 5.  We need to convert our current implementation using an acegi AuthenticationProvider to whatever is the new way of doing this.

Any pointers?   Thank you!
