Notice that the Simba driver URL uses properties passed to the URL. These can either come from the Driver->Parameters field or from a translation of the General->Principal field into properties. The Apache driver URL expects just the General->Principal information without translation. Additionally, we have to do checking to make sure that the properties are not set in both places - General->Principal and Driver->Parameters and throw error messages when both are empty or both have Kerberos values when saving the Server Properties window. We need to also do this checking when making a connection since the connection file might be old and has not been edited with the new checks.
