it works:
Result: Constraint violation (19)
Additional info: Password is not being changed from existing value
control: 1.3.6.1.4.1.42.2.27.8.5.1 false MAOBAQg=
ppolicy: error=8 (New password is in list of old passwords)

could anybody helps me, how can I catch the correct and accurate
error message?

if (PHP_VERSION_ID >= 70300) {
    $ctrl1 = array('oid' => LDAP_CONTROL_PASSWORDPOLICYREQUEST, 'value' => NULL, 'iscritical' => 0);
    $src = ldap_set_option($this->ldapconn, LDAP_OPT_SERVER_CONTROLS, array($ctrl1));
    $option = (LDAP_OPT_DIAGNOSTIC_MESSAGE | LDAP_OPT_ERROR_STRING); 
}
else {
    $option = LDAP_OPT_DIAGNOSTIC_MESSAGE;
}
ldap_get_option($this->ldapconn, $option, $_err);

but the $_err is a string:

string(49) "Password is not being changed from existing value"

There isn't the ppolicy error.

I've tried with values in ldap_set_option $ctrl:
value => 0, value => 0, iscritical => 1, and combinations of
these.
