What parts of Kerberos are/are not included with Mac OS X?
The Kerberos included with Mac OS X 10.2 and later includes the Kerberos framework, command line tools, the GUI Kerberos management application (although it’s hidden away in /System/Library/CoreServices ), a Kerberos login authenticator, and support for Kerberos in various applications. The CFM support libraries are not included, but can be obtained by installing the Mac OS X Kerberos Extras, which will also put an alias to the Kerberos application in a more convenient location. No Kerberos configuration information is included with Mac OS X (and only a sample configuration file is included with the Kerberos Extras), you must install a configuration for your site if your site does not have Kerberos auto-configuration/DNS setup (see below for more info).
