rh#1319616

It was reported that in all versions of MIT krb5, an authenticated attacker with permission to modify a principal entry can cause kadmind to dereference a null pointer by supplying an empty DB argument to the modify_principal command, if kadmind is configured to use the LDAP KDB module.
