I just installed and configured ArcGIS Enterprise 10.9 base deployment and also integrated window authentication with my organization's Active Directory. I can add portal user from our Active Directory and use regular window user account. The problem is that single-sign-on is not working, and I have enter my window username and pwd to login into portal. I like to get help on how to get single-sign-on to work for our ArcGIS portal. Thanks in advance for your help.
