I would like to use MVCForum as OpenID relaying party in order to leverage single sign-on functionality. The existing OpenID provider is already serving a bunch of different websites where single sign-on feature is used on all of them. MVCForum would join this cluster of websites and the use-case would be that MVCForum should not allow any other type of registration other than that leveraged by the OpenID provider.
Would this be doable with MVCForum v1.9.2 and has anyone already done it before? How much effort do you think this would require to implement? Any input would be appreciated.
