If you would like to work with Kerberos authentication then additional dependency is required on `libkrb5-dev` package.

Many of the Babelfish prerequisites are part of a typical Linux distribution. You may find that the packages on your distribution use a similar (but not identical) name.

To build Babelfish, you will need access to a user with root privileges, so you can convey privileges with `sudo`. You'll also need a non-root user to initialize the database; PostgreSQL does not allow a root user to own the `data` directory or start the server.

# How to build the Babelfish server with Kerberos authentication enabled

Please note that Kerberos authentication feature is available on Babelfish server with version 3.1.0 or higher.

1. To build the Babelfish server with Kerberos authentication enabled, you will need to install `build-essential` and `libkrb5-dev` packages.
2. Build the Babelfish server according to the instructions mentioned [here](https://github.com/babelfish-for-postgresql/babelfish_extensions/blob/BABEL_3_X_DEV/contrib/README.md#build-the-postgres-engine) and use --with-gssapi flag to configure Babelfish in order to enable the GSSAPI APIs.
