SUMMARY = "A network authentication protocol"
DESCRIPTION = "Kerberos is a system for authenticating users and services on a network. \
 Kerberos is a trusted third-party service.  That means that there is a \
 third party (the Kerberos server) that is trusted by all the entities on \
 the network (users and services, usually called "principals"). \
 . \
 This is the MIT reference implementation of Kerberos V5. \
 . \
 This package contains the Kerberos key server (KDC).  The KDC manages all \
 authentication credentials for a Kerberos realm, holds the master keys \
 for the realm, and responds to authentication requests.  This package \
 should be installed on both master and slave KDCs."
