Hi, After asking Unity about this error, they told me I had to add the following parameter on the JDBC URL, as well as adding the authSource - Windows: c:/temp/mongo.xml - Linux: /tmp/mong.xml This is a location on where to save the schema as a XML file. You can change it to whatever you want as well as the name of the file. They also told me that problem was that the default location for the file was not writeable, although they didn't tell me where was that location. This is an example that worked for me: jdbc:mongodb://user:password@host:port/database?schema=/tmp/mongo.xml&authSource=admin Regards, Jordi.
