I have noticed that companies using ADFS and Office 365 receive a custom login page when they type their e-mail address, consisting of a logo and a picture.
In a single ADFS deployment with multiple UPNs, can this be customised per @domain.com
I.e. If I type in email@example.com I get company1's template
I.e. If I type in firstname.lastname@example.org I get company2's template
Or is a separate ADFS deployment required to get a custom theme per company?
