clients	Kerberos V5 user programs (See User commands)
config	Configure scripts
config-files	Sample Kerberos configuration files
include	include files needed to build the Kerberos system
kadmin	Administrative interface to the Kerberos master database: kadmin, kdb5_util, ktutil.
kdc	Kerberos V5 Authentication Service and Key Distribution Center
lib	Libraries for use with/by Kerberos V5
plugins	Kerberos plugins directory
po	Localization infrastructure
prototype	Templates files containing the MIT copyright message and a placeholder for the title and description of the file.
slave	Utilities for propagating the database to slave KDCs kprop and kpropd
tests	Test suite
util	Various utilities for building/configuring the code, sending bug reports, etc.
windows	Source code for building Kerberos V5 on Windows (see windows/README)

lib

The lib directory contain several subdirectories as well as some definition and glue files.

• The apputils directory contains the code for the generic network servicing.
• The crypto subdirectory contains the Kerberos V5 encryption library.
• The gssapi library contains the Generic Security Services API, which is a library of commands to be used in secure client-server communication.
• The kadm5 directory contains the libraries for the KADM5 administration utilities.
• The Kerberos 5 database libraries are contained in kdb.
• The krb5 directory contains Kerberos 5 API.
• The rpc directory contains the API for the Kerberos Remote Procedure Call protocol.

util

The util directory contains several utility programs and libraries.

• the programs used to configure and build the code, such as autoconf, lndir, kbuild, reconf, and makedepend, are in this directory.
• the profile directory contains most of the functions which parse the Kerberos configuration files (krb5.conf and kdc.conf).
• the Kerberos error table library and utilities (et);
• the Sub-system library and utilities (ss);
• database utilities (db2);
• pseudo-terminal utilities (pty);
• bug-reporting program send-pr;
• a generic support library support used by several of our other libraries;
• the build infrastructure for building lightweight Kerberos client (collected-client-lib)
• the tool for validating Kerberos configuration files (confvalidator);
• the toolkit for kernel integrators for building krb5 code subsets (gss-kernel-lib);
• source code for building Kerberos V5 on MacOS (mac)
• Windows getopt operations (windows)
