AAD DS fully qualified domain name 15 characters limit is too short
I am trying to set up an application in azure and using AAD as authentication. the domain name we have is 16 characters before .com. we had to create a non-routable domain name in AAD DS because of the limit and now every one have to type longdomainname\username instead of their fully-routable email address. Not everyone can get a domain under 15 character so please increase the limit from 15 characters to at least 30. having a short limit kill the very purpose of having a single sign-on.
