I have implemented ADFS 4.0 on a corporate intranet using Windows Server 2016, but I am unhappy with how Microsoft provided logon page looks. I have customized some elements through the use of PowerShell, but what I really want to do is take a custom logon page I built using the bootstrap front-end framework and implement it as the ADFS logon page.
Is this possible with ADFS 3.0? This doesn't appear to be as straight forward as I would have though.
The only way to customise the login pages for any ADFS > v2 is to use onload.js.
