Description: Potentially incompatible upgrade
 You appear to be upgrading from a version of zephyr that uses
 Kerberos version 4 to authenticate.  Kerberos version 4 support has
 been removed from Debian, and accordingly from zephyr.  This version
 of zephyr uses Kerberos 5 to authenticate, and thus your servers must
 have been upgraded for it to be useful.
 .
 A server that authenticates both ways can be built for lenny from the
 zephyr source package, see:
   /usr/share/doc/libzephyr4-krb5/README.krb4-5
 .
 Continue with the upgrade?
