bakunin,
This appears to be a question that will never die.
I have since found a way (by creating a daemon that checks the logfile for any changes, every 20 seconds or so) to rig a solution, but everyone involved in the project keeps bringing up this trigger mechanism again and again.
It seems they are determined that I do it that way.
All I can say is one of the techs played around with this briefly and suggested creating a fifo pipe file. This is something I have never done, or been told to do, in about a decade and a half of UNIXing. Sorry, it just has never come up.
Apparently it works something like this:
#!/usr/bin/sh
exec 0 < log_pipe #log_pipe is a pipe made using the mkfifo cmd
while :
do
while read LINE
sleep 1
done
The only thing I can possibly understand about a fifo file is that it simply sits with the contents of one action and waits for another, such as:
ls | pg
you can mkfifo pipe_listing then:
ls > pipe_listing
then pg < pipe_listing sometime later.
Any of this make any sense?
Everyone says that they can't understand why I am not going htis route, but no one can say how................can't figure it out for anything................

warn.conf
warn.conf(4) File Formats warn.conf(4) NAME
warn.conf - Kerberos warning configuration file SYNOPSIS
/etc/krb5/warn.conf DESCRIPTION
The warn.conf file contains configuration information specifying how users will be warned by the ktkt_warnd daemon about ticket expiration on a Kerberos client. Credential expiration warnings are sent, by means of syslog, to auth.notice. All other warning messages are sent to daemon.notice. Each Kerberos client host must have a warn.conf file in order for users on that host to get Kerberos warnings from the client. Entries in the warn.conf file must have the following format: principal syslog | terminal | mail time [email_address] principal Specifies the principal name to be warned. The asterisk (*) wildcard can be used to specify groups of principals. syslog Sends the warnings to the system's syslog. Depending on the /etc/syslog.conf file, syslog entries are written to the /var/adm/messages file and/or displayed on the terminal. terminal Sends the warnings to display on the terminal. mail Sends the warnings as email to the address specified by email_address. time Specifies how much time before the TGT expires when a warning should be sent. The default time value is seconds, but you can specify h (hours) and m (minutes) after the number to specify other time values. email_address Specifies the email address at which to send the warnings. This field must be specified only with the mail field. EXAMPLES
Example 1: Specifying warnings The following warn.conf entry * syslog 5m specifies that warnings will be sent to the syslog five minutes before the expiration of the TGT for all principals. The form of the mes- sage is: jdb@ACME.COM: your kerberos credentials expire in 5 minutes FILES
