Kerberos only does authentication and not authorization, so it
only provides 1/2 (or 1/3) of the AAA puzzle. You still need
some authorization service such as LDAP or NIS or 411 to provide
the authorization information and it is not secure to house or
provide authentication information in NIS or LDAP or 411, though
a lot of people use LDAP to house Heimdal Kerberos secrets it
is not considered a fully secure implementation.
