Value cannot be empty. Parameter name: userName

Question

I am getting this error while logging with CME.

This is the complete error message:

System.ServiceModel.FaultException`1[Tridion.ContentManager.CoreService.Client.CoreServiceFault]: Value cannot be empty. Parameter name: userName. (Fault Detail is equal to Tridion.ContentManager.CoreService.Client.CoreServiceFault).

What does this error mean?
