Active Directory Integration / SAML

We are trying to setup Active Directory Single Sign On / SAML for Epicor Data Analytics (EDA). We followed these directions and feel that we set things up correctly. That is about the end of the documentation and as far as I got. Now I’m wondering how do we create accounts or give our domain users access to get into EDA? When I log in using my SSO, EDA takes me to the login screen. I don’t know how to move forward from here. Any help is appreciated.

I’ve found out that if you create a user account with the user name = the SSO uid then it should work. Mine user name is my work email address.

Now the question is can we auto provision through Azure?
