If access to that authentication domain on the Central Management Server has been verified outside of InfoScale Operations Manager, and all prerequisites for adding authentication domains to VIOM in the Administrator's Guide have been followed, the root cause of the login failure may be that the domain was not assigned the required permissions to access the entire Central Management Console.
Under the Permissions tab of Broker settings under Settings > Security in the Central Management Console, ensure all five roles specified in the tab (Server, Storage, Availability, Virtualization, and Management Server) are granted to the authentication domain.
