We deployed CRM 2016 and configured IFD as well but the issue we have noticed is if we explicitly mention "HTTP" protocol in org url then its not redirecting to ADFS sign in page. just a basic windows prompt leading with error 401.1 -
it does working fine and redirecting properly to adfs sign in page if we mention https. this behavior is only with CRM 2016. CRM 2011 / 2013 / 2015 properly push to ADFS sign in page even with http.
summary : CRM 2016 Only
http://org.rootdomin.com [not redirecting to adfs sign in page]
https://org.rootdomain.com [working fine.]
NOTE : both the combination [http and https] indeed working fine with CRM 2011, 2013 and 2015 update 0.2
To fix this situation we have temporally added http to https redirect Rewrite Rule hooked with CRM website.
is it a bug? or it is by design, if yes then why? what is the logic behind this...
thanks.
