Upgrading External Webauth

To upgrade External Webauth, do the following:

•

When upgrading wireless LAN controllers from operating system release 2.0 or 2.2.127.4 to release
3.0, update the external webauth configuration as follows:

–

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

config custom-web ext-webserver add <IP address>

(where <IP address> is the address of any web server that performs external web
authentication.)

•

Then, the network manager must use the new login_template which is included below:

<html>

<head>

<meta http-equiv="Pragma" content="no-cache"> <meta HTTP-EQUIV=”Content-Type”

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

function submitAction(){

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);

document.forms[0].redirect_url.value = redirectUrl;

}

document.forms[0].buttonClicked.value = 4;

document.forms[0].submit();

}

function loadAction(){

var url = window.location.href;

var args = new Object();

var query = location.search.substring(1);

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

for(var i=0;i<pairs.length;i++){

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);
