As a result, the best way to approach Kerberos client functionality in Mac OS X is to simply treat it as a special case of a generic MIT Kerberos client running Unix. However, there are a few quirks and some added functionality included with the Mac OS X implementation as compared to a stock MIT Kerberos 5 distribution.
First, while Kerberos is included with the base Mac OS X distribution, it is recommended that administrators install the MIT Kerberos Extras for Mac OS to add some of the functionality that was omitted from the Apple distribution (http://web.mit.edu/macdev/Development/MITKerberos/Common/Documentation/osx-kerberos-extras.html).
