    • createCredential

      public static MongoCredential createCredential(String userName, String database, char[] password)
      Creates a MongoCredential instance with an unspecified mechanism. The client will negotiate the best mechanism based on the version of the server that the client is authenticating to.

      If the server version is 4.0 or higher, the driver will negotiate with the server preferring the SCRAM-SHA-256 mechanism. 3.x servers will authenticate using SCRAM-SHA-1, older servers will authenticate using the MONGODB_CR mechanism.

      Parameters:
      userName - the user name
      database - the database where the user is defined
      password - the user's password
      Returns:
      the credential

    • createScramSha1Credential

      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 SCRAM-SHA-1 mechanism regardless of whether the server you are connecting to supports the authentication mechanism. Otherwise use the createCredential(String, String, char[]) method to allow the driver to negotiate the best mechanism based on the server version.
      Parameters:
      userName - the non-null user name
      source - the source where the user is defined.
      password - the non-null user password
      Returns:
      the credential

      2.13

    • createMongoX509Credential

      public static MongoCredential createMongoX509Credential()
      Creates a MongoCredential instance for the MongoDB X.509 protocol where the distinguished subject name of the client certificate acts as the userName.

      Available on MongoDB server versions >= 3.4.

      Returns:
      the credential

    • createPlainCredential

      public static MongoCredential createPlainCredential(String userName, String source, char[] password)
      Creates a MongoCredential instance for the PLAIN SASL mechanism.
      Parameters:
      userName - the non-null user name
      source - the source where the user is defined. This can be either "$external" or the name of a database.
      password - the non-null user password
      Returns:
      the credential

    • createGSSAPICredential

      public static MongoCredential createGSSAPICredential(String userName)
      Creates a MongoCredential instance for the GSSAPI SASL mechanism.

      To override the default service name of "mongodb", add a mechanism property with the name "SERVICE_NAME".

      To force canonicalization of the host name prior to authentication, add a mechanism property with the name "CANONICALIZE_HOST_NAME" with the valuetrue.

      To override the Subject with which the authentication executes, add a mechanism property with the name "JAVA_SUBJECT" with the value of a Subject instance.

      To override the properties of the SaslClient with which the authentication executes, add a mechanism property with the name "JAVA_SASL_CLIENT_PROPERTIES" with the value of a Map<String, Object> instance containing the necessary properties. This can be useful if the application is customizing the default SaslClientFactory.

      Parameters:
      userName - the non-null user name
      Returns:
      the credential
