Important Notes

Upgrading External Web Authentication

When upgrading a controller from operating system release 2.0 or 2.2.127.4 to release 3.2.116.21,
update the external web authentication configuration as follows:

Instead of using a preauthentication ACL, the network manager must configure the external web
server IP address using this command:

config custom-web ext-webserver add IP-address

Note

IP-address is the address of any web server that performs external web authentication.

The network manager must use the new login_template shown here:

<html>

<head>

CONTENT="text/html; charset=iso-8859-1"> <title>Web Authentication</title> <script>

var link = document.location.href;

var searchString = "redirect=";

var equalIndex = link.indexOf(searchString);

var redirectUrl = "";

var urlStr = "";

if(equalIndex > 0) {

equalIndex += searchString.length;

urlStr = link.substring(equalIndex);

if(urlStr.length > 0){

redirectUrl += urlStr;

if(redirectUrl.length > 255)

redirectUrl = redirectUrl.substring(0,255);

var pairs = query.split("&");

var pos = pairs[i].indexOf('=');

if(pos == -1) continue;

var argname = pairs[i].substring(0,pos);

var value = pairs[i].substring(pos+1);

args[argname] = unescape(value);

}

//alert( "AP MAC Address is " + args.ap_mac);

//alert( "The Switch URL is " + args.switch_url);

document.forms[0].action = args.switch_url;

// This is the status code returned from webauth login action

// Any value of status code from 1 to 5 is error condition and user

// should be shown error as below or modify the message as it suits
