NAME

       rlm_realm - FreeRADIUS Module

DESCRIPTION

       The  rlm_realm  module  parses  the  User-Name  attribute  into a User section and a Realm
       section.  This is used primarily in a proxy situation, however, Realms can  also  be  used
       locally to provide different service profiles based on the Realm being used.

       The main configuration items to be aware of are:

       format This  can be either 'prefix' or 'suffix'.  It specifies whether the Realm is before
              or after the User portion in the User-Name string.

       delimiter
              A single character in quotes, which  is  used  as  the  delimiting  character  that
              separates the Realm and User sections of the string.

       ignore_default
              This is set to either 'yes' or 'no'.  If set to 'yes', this will prevent the module
              instance from matching a realm against the DEFAULT entry.  This may  be  useful  if
              you have multiple realm module instances.  The default is 'no'.

       ignore_null
              This is set to either 'yes' or 'no'.  If set to 'yes', this will prevent the module
              instance from matching a realm against the NULL entry.  This may be useful  if  you
              have multiple realm module instances.  The default is 'no'.

       This  module  parses  the  realm  from  the  User-Name attrbiute according to the instance
       configuration,  and  then  performs  a  lookup  to  find   a   matching   realm   in   the
       '/etc/freeradius/3.0/proxy.conf'  file.   Depending  on  the configuration of the Realm as
       matched in the file, the username may be rewritten in a 'stripped'  format,  or  with  the
       Realm  portion  removed.   In  either  case, a Realm attribute is created and added to the
       packet on a match, which can be used by other modules.
