The authentication mechanism to use, selected from the following:

  • No Authentication (None)None: The connector does not authenticate the connection.
  • MongoDB User Name and Password (SCRAM-SHA-1)SCRAM-SHA-1: The connector authenticates the connection using the SCRAM-SHA-1 protocol, which is the default authentication protocol used by MongoDB.

    • Note:

    If authentication through SCRAM-SHA-1 fails, the connector automatically retries authentication using the MONGO-CR mechanism instead. MONGO-CR is deprecated as of MongoDB version 3.0.

  • SCRAM-SHA-256 (SCRAM-SHA-256)SCRAM-SHA-256: The connector authenticates the connection using the SCRAM-SHA-256 protocol.

    • Note:

    SCRAM-SHA-256 authentication is only supported on MongoDB version 4.0 and above.

  • Kerberos (GSSAPI)GSSAPI: The connector authenticates the connection using the Kerberos protocol.
  • LDAP (PLAIN)PLAIN: The connector authenticates the connection using the LDAP protocol.
