There are several free Kerberos implementations, but the most widely known are probably Heimdal and MIT. We primarily use MIT here at UMBC.

Installation

Here are links to the most popular Kerberos implementations. Follow their documentation in order to install Kerberos, or if your operating system distributes its own Kerberos implementation, consult that.

• Kerberos: The Network Authentication Protocol (MIT)

• The Heimdal Kerberos 5 Implementation

Configuration

Once you've installed Kerberos, you'll need to create a configuration file. On UNIX systems this file is typically /etc/krb5.conf, but the precise location may vary; refer to your implementation's documentation. Here is a minimal sample configuration that should get you going:

krb5.conf
