public static MongoCredential createScramSha1Credential(String userName,
String source,
char[] password)
Creates a MongoCredential instance for the SCRAM-SHA-1 SASL mechanism. Use this method only if you want to ensure that the driver uses the MONGODB_CR mechanism regardless of whether the server you are connecting to supports a more secure authentication mechanism. Otherwise use the createCredential(String, String, char[]) method to allow the driver to negotiate the best mechanism based on the server version.

In the above, MONGODB_CR should be replaced by SCRAM-SHA-1 SASL.
