Error AADSTS50126 / invalid_grant installing Azure AD Connect ErrorCode: invalid_grant StatusCode: 400
I encountered this error when deploying new Azure AD Connect instances to enable high availability for a customer. In the configuration step of the installation I received the following errors. I try to ad my admin account in exception but still I am getting the same error. I think It could be a compatibility of issue with MFA.
I did see any error or warning in event log except the below information:
Authenticate-ADAL: Interaction Required [interaction_required] – AADSTS50079: Due to a configuration change made by your administrator, or because you moved to a new location, you must enroll in multi-factor authentication to access ‘00000002-0000-0000-c000-000000000000’.
