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" or "false".  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".
