Make sure that your URL you are using for opening the Hub is part of your Intranet Sites. Then you should have the SSO experience out of the box in your IE and Google Chrome.

Let me know if you need more details on the Firefox use case or if IE and Chrome works jsut fine for you.

For a user with version 44 SSO still works.
We upgraded to SR12 recently.
Do you think this may have caused the issue?
