We've just licensed Xenforo, and it looks great. However, before we do a major site revamp for it, we'd like to tie all the services together. I'm looking for a PROVIDER plugin for SSO for xenoforo -- I don't care if it's openid, oauth2, LDAP, or what, just so long as it's SOME standard. Does anyone know of a published product for this? I'm aware of XenSSO (now Single Sign On Master by Waindig). I'm aware that Naatan was/is working on XenOpenID, but I have seen no further information there. Any help would be appreciated, whether it be links to projects, or information about people working on such a project.
