rlm_files: FreeRADIUS Module

NAME

rlm_files - FreeRADIUS Module

DESCRIPTION

The rlm_files module uses the 'users' file for accessing authorization information for users. Additionally, it supports a 'users' file syntax to be applied to the accounting and pre-proxy sections.

The main configuration items to be aware of are:

usersfile

The filename of the 'users' file, which is parsed during the authorization stage of this module.

acctusersfile

The filename of the 'users' file, which is parsed during the accounting stage of this module.

preproxy_usersfile

The filename of the 'users' file, which is parsed during the pre_proxy stage of this module.

compat

This option allows FreeRADIUS to parse an old style Cistron syntax. The default is 'no'. If you need to parse an old style Cistron file, set this option to 'cistron'.

key

This option lets you set the attribute to use as a key to find entries. The default is "%{%{Stripped-User-Name}:-%{User-Name}}". Note that the key MUST supply real data. Dynamic attributes like "Group" will not work, because the "Group" attribute can only be used as a comparison, to see if a user is in a Unix group. It will not return the name of the Unix group that a user is in.

If you want to use groups as a key, see the rlm_passwd, which will create a real attribute that contains the group name.

This configuration entry enables you to have configurations that perform per-group checks, and return per-group attributes, where the group membership is dynamically defined by a previous module. It also lets you do things like key off of attributes in the reply, and express policies like like "when I send replies containing attribute FOO with value BAR, do more checks, and maybe send additional attributes".
