365 ADFS white screen

We have office 365 in a ADFS enviroment.
Most items work excellent.

Issue is when users access online 365 content, like SharePoint, they get a white web page login asking for their address and password. (see attached)

Single Sign-On should be....well, Single.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That's FBA, which means that you have not configured properly the server and/or clients for true SSO. Make sure that Windows Integrated auth is enabled on the AD FS server, that its FQDN is added to the Local zone in IE and that WIA auth is enabled for that zone. Other browsers will require additional configuration as well.

Here's an example article: http://blogs.technet.com/b/abizerh/archive/2013/04/11/more-information-about-sso-experience-when-authenticating-via-adfs.aspx

This is what worked for us.

On your Federation server.
Web.config doc

      <add name="Forms" page="FormsSignIn.aspx" />      
      <add name="Integrated" page="auth/integrated/" />
       <add name="TlsClient" page="auth/sslclient/" />
      <add name="Basic" page="auth/basic/" />

Move “integrated” from second to first.

IE now skips any other sign-in prompts. Chrome too.
Fox still prompts, but I like it that way.
