Have enabled single sign-on for ADSSP and have also enabled SSL. But when accessing the server's URL (either via HTTP or HTTPS) the user is presented with a login screen (it is different to the standard login screen because the login form is below the Forogt Password / Account Unlock buttons, and also the image branding is the ADSSP image not our custom organization logo.

 

Wondering if anyone has seen this situation.

 

(Note: can't confirm, but I believe single sign-on was working prior to enabling SSL, that's why I mention it).
