* otherwise it calls kadm5_chpass_principal
*
* Arguments:
* principal (input) krb5_principals whose password we are
* changing
* keepold (input) whether to preserve old keys
* n_ks_tuple (input) the number of key-salt tuples in ks_tuple
* ks_tuple (input) array of tuples indicating the caller's
* requested enctypes/salttypes
* password (input) password we are going to change to.
* <return value> 0 on success error code on failure.
*
* Requires:
* kadm5_init to have been run.
*
* Effects:
* calls kadm5_chpass_principal which changes the kdb and the
* the admin db.
