I was redirected to this forum from a Microsoft moderator at the Office 365 forum. My question is about ADFS, specifically the ADFS Proxy component.
With activated Single Sign-On on an Office365 tenant is it possible to transfer the entered username onhttp://mail.office365.com/ to the username field of the ADFS proxy to which the user is redirected? It is inconvenient to enter the username twice, especially when the username is long in addition to the domain name. Of course it is possible to direct users straight to the proxy using a CNAME DNS record like mail.domain.com IN CNAME mail.office365.com, but anyway it would be good if redirection worked.
I saw this happening for the Office 365 subscriber kent.edu (Kent State University Ohio) at mail.office365.com. The username gets transferred to the username field on the proxy authentication page. Just entertest@kent.edu at mail.office365.com and you'll see what I mean. How can I enable that too? The ADFS proxy runs on Windows Server 2012.
Thank you in advance.
