44: <FONT SIZE=-1>From the original source web site:
45: <BR>"Kerberos is a system for authenticating users and services on a network. It is built upon the assumption that the network is "unsafe". For example, data sent over the network can be eavesdropped and altered, and addresses can also be faked. Therefore
46: they cannot be used for authentication purposes."

52: <P>
53: There are good RPMs for kerberos version 5, however many educational
54: institutions are only compatible with version 4 (and version 4 has its
55: advantages).
