IV. Radius

Introduction

About Radius

This package is based on the libradius of FreeBSD. This PECL adds full support for Radius Authentication (RFC 2865) and Radius Accounting (RFC 2866). This package is available for Unix (tested on FreeBSD and Linux) and for Windows.

Note: An exact description for libradius can be found here. A detailed description of the configuration file can be found here.

Install

Howto install the package?

or if you would like to have it as .so:

  • untar the package

  • run phpize in the radius-x.x directory

  • run ./configure in the radius-x.x directory

  • make; make install

for windows I recommend to use the php_radius.dll from here

Quickstart

Howto start?

Take also a look at the examples in this package.

The package contains an example php script. This script demonstrates howto authenticate with radius using PAP or CHAP (md5). If you authenticate with MSoft Radius servers then its not possible to use CHAP (md5). If you would like to authenticate with MSoft Servers you have to use MS-CHAPv1 or MS-CHAPv2, but its more complicated, because you need md4, sha1 and des to generate the right data. The enclosed examples demonstrate all authentication-methods, including MS-CHAPv1 and MS-CHAPv2. To get the MS-CHAP to work you need the mcrypt and the mhash extension, starting with version 1.2 of the package, the mcrypt extension is no longer needed.
