NAME

       rlm_unix - FreeRADIUS Module

DESCRIPTION

       The rlm_unix module reads crypt(3) passwords from the system password file, and allows the
       server to use them for authentication.  The module also provides FreeRADIUS  an  interface
       into a radwtmp file (used by "radlast") when added to the accounting section.

       The  rlm_unix module does provides the functionality for "Auth-Type = System".  The module
       should be listed in the "authenticate"  section.   Please  see  the  default  radiusd.conf
       shipped with the server for an example of the correct usage of this module.

       As of FreeRADIUS 1.1.0, the module no longer reads, or caches /etc/passwd, /etc/shadow, or
       /etc/group.  If you wish to  cache  those  files,  see  rlm_passwd.   Most,  if  not  all,
       configurations should not need those files to be cached.

       The main configuration items to be aware of are:

       radwtmp
              The  path  to  the  system  wtmp file to be used for keeping the database of online
              users as read by the 'radlast' program.
