I need to share login credntials for applications accross domains that do not have a common ancestor, e.g.
There is no way to set a cookie that is included in requests to both these domains.
In this case we need a third server, the SSO server, whose purpose is to keep track of who is logged in. When you visit a page on secrets.com, if its cookie is not set, it consults the SSO server to find if the user is already logged in, in which case it silently creates the cookie and carries on as if they had already been logged in.
Can anyone reommend a way to do this via .net - or if there are any open source solutions to do this ?
