How to configure single-sign-on for ArcGIS Enterprise base deployment ?

[JohnHu]

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.

Hi Grant
i believe you don't need to have the https://   
and you certainly don't need the full URI including webadaptorname
can you try *.domain.com ?  - that would be a typical entry
