Ok have had the DAG running with AD for a couple of weeks, I have used the full outlook client, logged into the dag and access sharepoint online with 2FA. This morning I rebooted and got prompted by Skype for Business to Login, clicked on my name, DAG login pops up enter username and password, 2FA pops up, push to my phone, hit accept, and get this error in skype.
You didn’t get signed in. It might be your sign-in address or logon credentials, so try those again. Did try, same thing.
Modern Auth is turned on for Skype, double checked it.
