Hello, My organization is considering xenForo as our forums solution. As such, I am charged with evaluating whether and how we can enable our users to SSO from our extranet to xenForo forums. I do not see much documenation on this on this topic. My question is, does xenForo have an API (OpenID, SAML, OAuth, etc.) for SSO, and where can I find documentation on how to do it? Thanks!
