Authenticate incoming OpenVPN connections.

This project is a core piece of the OpenVPN-Access project. It intercepts all incoming OpenVPN connections and verifies the provided usernames and passwords against those stored in a MariaDB database.

This project is part of the OpenVPN Access eco-system. Be sure to check out the main repository to get started.

Building from Source

OpenVPN-Authenticator uses cmake to create its build files and configurations, and depends on the following pieces of software:

• Googletest to build and run tests (optional).
• libbcrypt to verify passwords against their hashed versions in the database.
• mariadbpp to connect to the MariaDB database instance.
• yaml-cpp to parse authenticator configuration files.

These, however, are all pulled from their GitHub repositories at compile time by cmake, so there is no need to install them beforehand.

To build OpenVPN-Authenticator, you will need:

• A C++20 compatible compiler. We recommend g++.
• cmake to generate build files.
• doxygen to generate documentation files (optional).

If you meet these requirements, building OpenVPN-Authenticator is as simple as:

mkdir build && cd build
cmake ..
cmake --build .

If you have any problems, questions or comments, please don't hesitate to open an issue, or contact us on mattermost.

Documentation

OpenVPN-Authenticator is well documented in-source, but for the sake of completion, you can find a full doxygen generated HTML documentation site here.
