Troubleshooting

If you get an exception like this:

23:16:24 - [LLOGIN SERVICE]: Exception processing login for Ruth OpenSim: System.ArgumentException: Object type System.Guid cannot be converted to target type: System.String
Parameter name: val
at System.Reflection.MonoField.SetValue (System.Object obj, System.Object val, BindingFlags invokeAttr, System.Reflection.Binder binder,  System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0

Try adding this to your database connection string: ConnectionString = "Data Source=localhost;Database=opensim;User ID=opensim;Password=*****;Old Guids=true;"
