NAME

       inn-radius.conf - Configuration for nnrpd RADIUS authenticator

DESCRIPTION

       This describes the format and attributes of the configuration file for the nnrpd RADIUS authenticator.
       See radius(8) for more information about the authenticator program.  The default location for this file
       is inn-radius.conf in pathetc.

       Blank lines and lines beginning with "#" are ignored, as is anything after a "#" on a line.  All other
       lines should begin with a parameter name followed by a colon and the value of that key, except that each
       section of configuration for a particular server should be enclosed in:

           server <name> {
               # parameters...
           }

       where <name> is just some convenient label for that server.

SERVER GROUP PARAMETERS

       The available parameters are:

       radhost
           The hostname of the RADIUS server to use for authentication.  This parameter must be set.

       radport
           The port to query on the RADIUS server.  Defaults to 1645 if not set.

       lochost
           The hostname or IP address making the request.  The RADIUS server expects an IP address; a hostname
           will be translated into an IP address with gethostbyname().  If not given, this information isn't
           included in the request (not all RADIUS setups require this information).

       locport
           The port the client being authenticated is connecting to.  If not given, defaults to 119.  This
           doesn't need to be set unless readers are connecting to a non-standard port.

       secret
           The shared secret with the RADIUS server.  If your secret includes spaces, tabs, or "#", be sure to
           include it in double quotes.  This parameter must be set.

       prefix
           Prepend the value of this parameter to all usernames before passing them to the RADIUS server.  Can
           be used to prepend something like "news-" to all usernames in order to put news users into a
           different namespace from other accounts served by the same server.  If not set, nothing is prepended.

       suffix
           Append the value of this parameter to all usernames before passing them to the RADIUS server.  This
           is often something like "@example.com", depending on how your RADIUS server is set up.  If not set,
           nothing is appended.

       ignore-source
           Can be set to "true", "yes", "on", "false", "no" or "off".  If set to false, the RADIUS authenticator
           will check to ensure that the response it receives is from the same IP address as it sent the request
           to (for some added security).  If set to true, it will skip this verification check (if your RADIUS
           server has multiple IP addresses or if other odd things are going on, it may be perfectly normal for
           the response to come from a different IP address).

EXAMPLE

       Here is a configuration for a news server named news.example.com, authenticating users against
       radius.example.com and appending "@example.com" to all client-supplied usernames before passing them to
       the RADIUS server:

           server example {
               radhost: radius.example.com
               lochost: news.example.com
               secret: IamARADIUSsecRET
               suffix: @example.com
           }

       The shared secret with the RADIUS server is "IamARADIUSsecRET".
