I have 2 subdomain prousers.example.com normalusers.example.com now I want two different authentication system for both but I just drowned in bugs and errors so complex for me. Can anybody help? just two simple authentication system for each subs. a sample form with one filed no need database no need any validation I just want to figure out how the session management works in this case ( if user logged on first sub they shouldn't access the other sub dashboard unless sign up there too )
