C Authentication Plugin

New in version 2.2.

The MongoDB Connector for BI provides a MySQL authentication plugin which implements the client side of MongoDB-supported authentication mechanisms. The mongosql_auth plugin allows you to use MongoDB Connector for BI with a MongoDB instance running with authentication enabled without needing to generate your own SSL certificates for authentication.

This plugin supports the following authentication mechanisms:



  • The SCRAM-SHA-1 mechanism hashes the passwords in the client plugin; however, all other data is in cleartext. If possible, use with encrypted connections.
  • The PLAIN mechanism sends the password in cleartext. Use encrypted connections with the PLAIN mechanism .

Supported Platforms

The plugin is built and tested on the following platforms:

  • Windows 2008 R2 (32- and 64-bit)
  • macOS 10.12 (64-bit)
  • Ubuntu 14.04 (64-bit)
  • RHEL 7.0 (64-bit)

Testing Environment

The plugin was developed against MySQL 5.7.18 Community Edition (64-bit), and tested with MySQL 5.7.18 Community Edition and the MongoDB Connector for BI 2.2+.
