| Kerberos for Macintosh Product Overview

> Kerberos for Macintosh (KfM) is the reference implementation of the Kerberos authentication system for Mac OS X. KfM provides support for both Kerberos protocol versions, all the major Kerberos APIs and wraps it all into a simple Macintosh package with support for Mac OS X, as well as legacy support for Mac OS 8 & 9 and the Classic environment under Mac OS X.

> Under the hood, Kerberos for Macintosh provides Kerberos v5 and Kerberos v4 protocols, GSSAPI, an in-memory ticket cache, KClient compatibility and a graphical Login interface and accompanying API for acquiring Kerberos tickets.

> The current release of Kerberos for Macintosh for Mac OS X 10.3 (Panther) is 5.0, included with Mac OS X 10.3.x.
> The last release of Kerberos for Macintosh for Mac OS X 10.2 (Jaguar) was 4.5.1, included with Mac OS X 10.2.x.
> The Mac OS X Kerberos Extras for 10.2 and 10.3 are available from MIT.

> The last release of Kerberos for Macintosh supporting Mac OS X 10.1 was 4.0.3.
> The last release of Kerberos for Macintosh supporting Mac OS 8 & 9 and the Classic environment of Mac OS X was version 4.0.3.
