Not really. Kerberos and NIS are both in the Handbook, and as I
mentioned above I just changed the /var/yp/master.passwd that NIS was
working off of to have 'krb5' in the password field.

A quick bit of Google spelunking dug up some references but no
"HowTos". The RedHat Security Guide mentions it explicitly in the NIS
section, for example.

Normally NIS is a pain between different Unix implementations (due to
the different passwd designs such as DES vs. MD5). When using Kerberos
to handle the authentication, those problems go away. On the other
handle, you get to learn how to install NIS and Kerberos on multiple
operating systems :-)
