We too are facing the exact error message on arcgis enterprise 11.0 

SDE connection works properly for connecting with database. We are using a single domain user for this enterprise account.. The error msg also does not specify the actual root cause hence we are struggling from last 3 days to resolve this issue...

Any help on this will be highly appreciated....
