I was attempting to perform a db.auth() or authenticate command through the driver 3.6.1 and got the following error.

Error: com.mongodb.MongoCommandException: Command failed with error 2: 'Challenge-response authentication using getnonce and authenticate commands is disabled.' on server maas-gt-d4-u0038.nam.nsroot.net:37017. The full response is { "ok" : 0.0, "errmsg" : "Challenge-response authentication using getnonce and authenticate commands is disabled.", "code" : 2, "codeName" : "BadValue" }

My Code

mongodb://<user>:<pwd>@maas-gt-d4-u0038.nam.nsroot.net:37017/?ssl=true&authSource=admin&sslInvalidHostNameAllowed=true&authMechanism=SCRAM-SHA-1

       MongoDatabase mongoDB = mongoClient.getDatabase(databaseName);

       Document doc = mongoDB.runCommand(NativeAuthenticationHelper.getNonceCommand());

       BsonDocument auth = NativeAuthenticationHelper.getAuthCommand(<my user>, <my password>.toCharArray(), doc.getString("nonce"));

       Document res = mongoDB.runCommand(auth);

I am able to connect to the MongoDB instance with that string from my local Tomcat application. SCRAM-SHA-1 is being used.

Thanks & Regards,
