/etc/inc/util.inc 26.03.01 Code

function cisco_extract_index($prule) {
	$index = explode("#", $prule);
	if (is_numeric($index[1])) {
		return intval($index[1]);
	} else {
		logger(LOG_WARNING, localize_text("Error parsing RADIUS attribute - rule %s %s: Could not extract index", $prule));
	}
	return -1;;
}

In my older version before localize_text was introduced i was getting an error but Openvpn would continue on as the Cisco radius attributes are not needed for openvpn authentication.

Error parsing rule shell:priv-lvl: Could not extract index

/etc/inc/util.inc 25.11 Code

function cisco_extract_index($prule) {
	$index = explode("#", $prule);
	if (is_numeric($index[1])) {
		return intval($index[1]);
	} else {
		syslog(LOG_WARNING, "Error parsing rule {$prule}: Could not extract index");
	}
	return -1;;
}

However in 26.03.01 it's crashing at the log message due to too many placeholders, $prule for me is just a string "shell:priv-lvl"
