We currently have claims based ASP.Net websites integrated with ADFS 2.0. The LS website has been heavily customized for functionality and look & feel. There is also a vendor web site dependent on the single sign on functionality. Our company is moving the applications to cloud and the servers are windows server 2012. It comes with ADFS 3.0 and I've been told that we cannot go back to ADFS 2.0. Since ADFS 3.0 does nto support code customization of login pages, I'm not sure how to incorporate the existing functionality into ADFS 3.0. Please point me to right articles -
1. Can we build our own login pages in website and use javascript to post to adfs 3.0? Will it be able to handle password expired scenarios?
2. Can we build our own authentication solution (SAML) around adfs 3.0?
3. Or Is it possible to install ADFS 2.0 on windows server 2012?
