Display ADFS 2.0 Forms Authentication Login Page Instead of Windows Authentication Prompt
After installing ADFS 2.0 for SharePoint a Windows login prompt was shown when the SharePoint site forwarded to the ADFS server instead of the ADFS Forms Authentication login screen.
The reason for this is that the ADFS website tries to use Windows Authentication before trying to use the Forms authentication which displays the loging page below.
No matter what account I tried to use here I would eventually receive a 401 Not Auhorized error.

Forms Login Screen for ADFS 2.0 |
To fix this do the following on the ADFS server:
1. Open IIS and Explore under Default Website\adfs\ls
2. Open the web.config file with Notepad, look for the localAuthenticationTypes section.
3. Move the line for Forms above the line for Integrated and save the web.config file. This will force the ADFS application to use the Login Page authentication before trying to use Windows Authentication.

This is no solution to mix.
I was actually having the inverse issue where internal users would get Integrated Auth and external would have Forms from the ADFS Proxy. Moving the basic before the forms on the Proxy gives them a similar experience.
Thanks!

one is for normal browser, another is for mobile browser.
Can I add two in web.config
Is it possible for adfs server to use Forms authentication or we have to take adfs server proxy for Forms Authentication ?
Thanks in advance

This wasn't my exact issue but got me going in the right direction on my issue.
Thanks for taking the time to document this so clearly.
By the way, is there a way we can have the signed in windows users auto-login to the websites?
If I use below snippet in config() method of spring security configuration, will it be work for me as well?
-> http.formLogin().loginPage("/saml/login");
