## Overview

26
27
28
29
This module installs and configures [FreeRADIUS](http://freeradius.org/) server
on Linux. This module was written for use with FreeRADIUS 2.x and has not been
tested with FreeRADIUS 3.x. It was designed with CentOS in mind but should
work on other distributions.
30
31
32

## Module Description

33
34
35
36
37
38
This module installs FreeRADIUS from a distro-provided package and installs a
number of customised config files to enable flexibility. It then provides some
helpers to allow you to easily configure virtual servers (sites), modules, clients
and other config items. Most of these items accept a flat config file which you
supply either as a static file or a template - similar to the `source` and `content`
parameters in Puppet's `file` resource.
39

40
41
42
This module is designed to make it more straightforward for RADIUS administrators to
deploy RADIUS servers using Puppet. This module does not serve as a wizard and does
not avoid having to have an understanding of FreeRADIUS.

45
## Usage
46

47
This module provides several classes and defined types which take parameters.
48

49
### Classes
50

51
#### `freeradius`
52

53
54
The `freeradius` class installs the base server. In the early releases, this class does not
have many parameters as most values are hard-coded. I am working on parameterising more
55
56
of the global settings to increase flexibility. Patches are welcome.

82
##### `control_socket`
Enable the control-socket virtual server. See also the "radmin" program. Default: `false`

The maximum number of requests which the server keeps track of. This should be 256 multiplied by the number of clients. Default: `4096`

##### `max_servers`
Limit on the total number of servers running. Default: `4096`

##### `mysql_support`
Install support for MySQL. Default: `false`

##### `ldap_support`
Install support for LDAP. Default: `false`

##### `wpa_supplicant`.
Install wpa_supplicant utility. Default: `false`

##### `winbind_support`.
Add the radius user to the winbind privileged group. You must install winbind separately. Default: `false`.

156
##### `ip`
Default: `undef`. The IP address of the client.  For IPv6, use `ipv6addr`. `ip` and `ip6` are mutually exclusive but one must be supplied.

##### `ip6`
Default: `undef`. The IPv6 address of the client. `ip` and `ip6` are mutually exclusive but one must be supplied.

##### `net`
Default: `undef`. The netmask of the client, specified as an integer, e.g. `24`

##### `shortname`
required. A short alias that is used in place of the IP address or fully qualified hostname provided in the first line of the section.

##### `secret`
required. The RADIUS shared secret used for communication between the client/NAS and the RADIUS server.

##### `server`
Default: `undef`

##### `virtual_server`
Default: `undef`. The virtual server that traffic from this client should be sent to.

##### `nastype`
Default: `undef`. The nastype attribute is used to tell the checkrad.pl script which NAS-specific method it should use when checking simultaneous use.

##### `netmask`
Default: `undef`. The netmask of the client, specified as an integer, e.g. `24`

##### `redirect`
Default: `undef`

##### `port`
Default: `undef`. The UDP port that this virtual server should listen on. Leave blank if this client is not tied to a virtual server.

##### `srcip`
Default: `undef`
157
158

#### `freeradius::config`

## Limitations

251
This module is targeted at FreeRADIUS 2.x running on CentOS 6. It has not been tested
252
253
on other distributions, but might work. Likely sticking points with other distros are
the names of packages, services and file paths.
254

255
256
257
258
259
260
This module has not been tested on FreeRADIUS 3.x and almost certainly won't work
without modification. FreeRADIUS 3.x support in this module will come onto the roadmap
at the same time that my employer decides to start looking FreeRADIUS 3.x.

This module was written for use with Puppet 3.6 and 3.7, but should be quite agnostic
to new versions of Puppet.
261
262
263

## Development

264
265
266
267
This module was written primarily for internal use - features we haven't needed to
use probably haven't been written. Please send pull requests with new features and
bug fixes. You are also welcome to file issues but I make no guarantees of
development effort if the features aren't useful to my employer.
