By default Windows Server 2012 R2 ADFS 3.0 Setup Doesn’t support Edge Browsers.
To Add Support –
Set-ADFSProperties –ExtendedProtectionTokenCheck None
Get Properties –
Get-ADFSProperties | Select -ExpandProperty WIASupportedUserAgents
$Props=Get-ADFSProperties | Select -ExpandProperty WIASupportedUserAgents $Props=$Props+"Mozilla/5.0" $Props=$Props+"Edge/12" $Props=$Props+"Edge/14" $Props Set-ADFSProperties -WIASupportedUserAgents $Props Restart-Service adfssrv
- Still Edge Private mode gives ADFS Basic authentication prompt. (No fix found so far)
