Name:
Dapphp\Radius - A pure PHP RADIUS client based on the SysCo/al implementation, (*2)
Author:
Description:
Dapphp\Radius is a pure PHP RADIUS client for authenticating users against
a RADIUS server in PHP. It currently supports basic RADIUS auth using PAP,
CHAP (MD5), MSCHAP v1, and EAP-MSCHAP v2. The current 2.5.x branch is tested
to work with the following RADIUS servers:, (*3)
- Microsoft Windows Server 2019 Network Policy Server
- Microsoft Windows Server 2016 Network Policy Server
- Microsoft Windows Server 2012 Network Policy Server
- FreeRADIUS 2 and above
PAP authentication has been tested on:, (*4)
- Microsoft Radius server IAS
- Mideye RADIUS Server
- Radl
- RSA SecurID
- VASCO Middleware 3.0 server
- WinRadius
- ZyXEL ZyWALL OTP
The PHP openssl extension is required if using MSCHAP v1 or v2. For older PHP
versions that have mcrypt without openssl support, then mcrypt is used., (*5)
Installation:
The recommended way to install dapphp/radius is using Composer.
If you are already using composer, simple run composer require dapphp/radius or add
dapphp/radius to your composer.json file's require section., (*6)
Standalone installation is also supported and a SPL autoloader is provided.
(Don't use the standalone autoloader if you're using Composer!)., (*7)
To install standalone, download the release archive and extract to a location
on your server. In your application, require_once 'radius/autoload.php'; and
then you can use the class., (*8)
Examples:
See the examples/ directory for working examples. The RADIUS server address, secret, and credentials are read from
environment variables and default to:, (*9)
RADIUS_SERVER_ADDR=192.168.0.20
RADIUS_USER=nemo
RADIUS_PASS=arctangent
RADIUS_SECRET=xyzzy5461
To print RADIUS debug info, specify the -v option., (*10)
Example:, (*11)
RADIUS_SERVER_ADDR=10.0.100.1 RADIUS_USER=radtest php example/client.php -v
Synopsis:
<?php
use Dapphp\Radius\Radius;
require_once '/path/to/radius/autoload.php';
// or, if using composer
require_once '/path/to/vendor/autoload.php';
$client = new Radius();
// set server, secret, and basic attributes
$client->setServer('12.34.56.78') // RADIUS server address
->setSecret('radius shared secret')
->setNasIpAddress('10.0.1.2') // NAS server address
->setAttribute(32, 'login'); // NAS identifier
// PAP authentication; returns true if successful, false otherwise
$authenticated = $client->accessRequest($username, $password);
// CHAP-MD5 authentication
$client->setChapPassword($password); // set chap password
$authenticated = $client->accessRequest($username); // authenticate, don't specify pw here
// MSCHAP v1 authentication
$client->setMSChapPassword($password); // set ms chap password (uses openssl or mcrypt)
$authenticated = $client->accessRequest($username);
// EAP-MSCHAP v2 authentication
$authenticated = $client->accessRequestEapMsChapV2($username, $password);
if ($authenticated === false) {
// false returned on failure
echo sprintf(
"Access-Request failed with error %d (%s).\n",
$client->getErrorCode(),
$client->getErrorMessage()
);
} else {
// access request was accepted - client authenticated successfully
echo "Success! Received Access-Accept response from RADIUS server.\n";
}
Advanced Usage:
// Authenticating against a RADIUS cluster (each server needs the same secret).
// Each server in the list is tried until auth success or failure. The
// next server is tried on timeout or other error.
// Set the secret and any required attributes first.
$servers = [ 'server1.radius.domain', 'server2.radius.domain' ];
// or
$servers = gethostbynamel("radius.site.domain"); // gets list of IPv4 addresses to a given host
$authenticated = $client->accessRequestList($servers, $username, $password);
// or
$authenticated = $client->accessRequestEapMsChapV2List($servers, $username, $password);
// Setting vendor specific attributes
// Many vendor IDs are available in \Dapphp\Radius\VendorId
// e.g. \Dapphp\Radius\VendorId::MICROSOFT
$client->setVendorSpecificAttribute($vendorId, $attributeNumber, $rawValue);
// Retrieving attributes from RADIUS responses after receiving a failure or success response
$value = $client->getAttribute($attributeId);
// Get an array of all received attributes
$attributes = getReceivedAttributes();
// Debugging
// Prior to sending a request, call
$client->setDebug(true); // enable debug output on console
// Shows what attributes are sent and received, and info about the request/response
Requirements:
TODO:
- Set attributes by name, rather than number
- Vendor specific attribute dictionaries?
- Test with more implementations and confirm working
- Accounting?
