I have inherited a few systems that were set with a strange IFD setup
the most commom effects are dowble authentication or windows prompt that does not work and throw a
HTTP Error 401 - Unauthorized: Access is denied
I believe the issue is with a proxy or firewall that receives the external url and redirect to a internal crm url like localhos:5555
is there a practical way to track where it is breaking?
I know a proper ifd will have federation services, but what could cause the send windows prompt to do not recognize the AD password?
