Debugging files for MIT Kerberos 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 debugging information for the MIT Kerberos libraries. Install this package if you need to trace problems inside the MIT Kerberos libraries with a debugger.
