MIT Kerberos 1.3.1 (or a suitably recent Heimdal) is the minimum we have
maintained since Samba 3.0.  Using less than this will cause issues with
clients that for one reason or another do not posses 'DES' kerberos

Kerberos library requirements have been quite a pain in Samba 3.0.
There are three basic solutions:

 - Upgrade your OS to one with a suitable kerberos
 - Upgrade the kerberos libraries on your OS
 - Statically link your Samba install to an upgraded kerberos.  

The latter option is what SerNet did/does for their Samba 3.0 packages.

In Samba4, we have noted the pain that kerberos has caused in Samba 3.0,
and the current plan is to ship with a built-in kerberos library.
(Options for later development allow this to possibly use a system lib,
but the aim is to shift the pain away from the administrator, who can't
help the situation much).
