I have setup Azure AD Connect, can validate the AD replications of users (from on prem) appear in the Azure AD portal. All 'looks well' however, I cannot seem to be able to logon with these Azure AD users. The Azure AD users that I created via the Azure Portal CAN logon to Azure AD Joined machines. These same users however, cannot logon to on premises workstations that are domain joined.
I have tried doing a password reset, validated the users can logon to portal.azure.com with password, can logon to Azure AD joined machine, but with on premises workstation, the message is 'incorrect username/password".
Thanks in advance for any/all help.
