 Description:
 
 If you change the auth method in /etc/inetd.conf, killall -hup inetd, 
 inetd doesn't start using the new auth method.  it continues to use 
 the old.
 
 How-To-Repeat: 
 
 Set auth method to be:
 
 auth stream  tcp  nowait  root internal  auth -r -f -n -o UNKNOWN -t 30
 
 ensure auth is working properly.
 
 Then change the auth method to be:
 
 auth    stream  tcp     nowait  nobody /usr/local/etc/ident.sh     auth
 
 where /usr/local/etc/ident.sh is:
 
 #!/bin/sh
 ident=`/bin/date +%s`
 xxx=`/usr/bin/head -c 11`
 echo $xxx : USERID:UNIX:$ident
 
 then killall -hup inetd
 
  $ telnet 192.168.0.20 113

 That's the old auth.  There's no way the shell script can produce that.
