The problem is related with user forest but should be resource forest. By default AAD DS configured as user forest.
'Windows authentication' to the 'MS SQL Server' in AWS instance (Windows Server 2019) joined to the Azure AD DS 'management.com' domain from on-premise AD 'green.orange.com'.
- On-premise AD domain 'green.orange.com' with installed Azure AD Connect.
- Azure domain 'management.com'.
- AWS Domain joined instance to the 'management.com'.
- MS SQL Server with a Mixed authentication.
AWS instance joined to the AAD DS with a 'management.com' domain and can retrieve 'Objects & Users' from on-premise AD 'green.orange.com'.
When I do a connection through the 'Microsoft SQL Server Management Studio' to the 'SQL Server' joined to the 'management.com' domain from on-premise AD infrastructure I getting such messages:
SQL Server authentication - success;
Windows Authentication : Login failed. The login is from an untrusted domain and cannot be used with Integrated authentication. (.Net SqlClient Data Provider) [Error 18452].
Azure Active Directory - Password : A connection was successfully established with the server, but then an error occurred during the login process.
Azure Active Directory - Integrated : A connection was successfully established with the server, but then an error occurred during the login process.
How to allow access with Windows Auth. How to create a trust between two domains on-pem. & AAD DS (SPNs/Kerberos)?
Thank you!
