ADFS seems to be the preferred method of authentication for SSO. I have it working with ADFS 2.0, but there really isnt a proper fallback method for users to do forms based auth (or even get a prompt) Our situation is kind of unique in that we have users from two other organizations who connect to our network. So effectively I want user1@domain1.com to have SSO , and if user2@domain2.com or user3@domain3.com tries to login they get prompted for their credentials for domain1.com (its a strange setup... but i have no say in that matter).
Would enabling forms and windows integrated auth work in this case? Or would it still simply grab the credentials for user2@domain2.com and fail because it cant find it? Also, if theres an alternative method where they would simply get prompted with an ugly browser based login, I'd love to hear that as well!
Thanks!
