Hello all, I am hoping someone has seen something similar before. I have a web server with an app configured to use SSO. If a user browses to it via its hostname name with out the fqdn appended. The application signs the user in as expected. If you use hostname.domain.com it prompts for windows authentication. Even stranger still is if you are on the server locally and browse to https://localhost it works as expected, but if you use https://127.0.0.1 it again prompts for windows authentication. Has anyone ever seen this type of behavior?

How your domain setting? Did you have windows authentication enabled on the domain causing the credentials to be required when using the FQDN?
