Here is my situation. I have a cms framework that has membership/roles already integrated. I also have this framework on 3 domains sharing one database on another domain - this is where the aMember site resides. What i want to do is use the signup ability from aMember and alongside it control the members / roles from current sites. This cms is not a well known cms so there is no api built for it. Is what i am trying to do possible? Do i have to put the protected pages behind aMember or is that the only way it will work?
