ALWAYS module configuration.

0. INTRODUCTION

  The 'always' module will always return the same thing, regardless of
  how it's used.

1. CONFIGURATION

  The module has 3 configuration items:

	rcode = <status>

  Where <status> can be one of:

	reject			reject the request
	fail			fail to handle the request
	ok			the request was handled OK.
	handled			stop doing any more processing, as the
				module has "handled" the request itself.
	invalid			some bad configuration was encountered
	userlock		the user is locked out
	notfound		the user was not found
	noop			the module did nothing
	updated			the module touched the request


  The return codes can be used to change the default results of
  configurable fail-over.  (See 'configurable_failover' in this
  directory.)  For example, the configurable fail-over documentation
  has an example which is:

#----
  modules {
    sql sql1 {
      server="myfirstserver.example"
      # Insert other necessary parameters here
    }
    sql sql2 {
      server="mysecondserver.example"
      # Insert other necessary parameters here
    }
    always handled {
      rcode = handled
    }
  }
  authenticate {
    authtype SQL {
      redundant {
        sql1			# try module sql1
        sql2			# if that's down, try module sql2
	handled			# otherwise the request is "handled"
      }
    }
  }
#----

  This configuration says:

  Try module sql1.  If that's down, try module sql2, if that's down,
  then the 'always' module will mark the request as 'handled', and the
  server will stop ALL processing, INCLUDING any response to the
  client.

  This allows you to configure the server to have it appear to be
  down (i.e. not responding to requests) when the SQL servers which it
  depends on are down.  When the SQL servers come back up, then the
  RADIUS server will also start responding to requests.

  During this time, the server WILL respond to Status-Server messages,
  although that may not be a good idea.


  The other two configuration entries are for testing
  Simultaneous-Use.  They probably shouldn't be used.
