* hist_db krb5_db_entry of the history principal
* hist_key krb5_keyblock holding the history principal's key

* hist_kvno the version number of the history key
*
* If the history principal does not already exist, this function
* attempts to create it with kadm5_create_principal. WARNING!
* If the history principal is deleted and this function is executed
* (by kadmind, or kadmin.local, or anything else with permission),
* the principal will be assigned a new random key and all existing
* password history information will become useless.
