=head1 NAME
jpegDisplay.pl - A script to display a jpeg picture from jpegPhoto attribute of a LDAP directory entry.
=head1 SYNOPSIS
The intent of this script is to show the user how to retrieve and
display a jpeg photo from a LDAP directory entry.
This script has been tested on a OpenLDAP 2.0.7 directory server
and a Netscape 4.x LDAP directory server.
You may need to change the first line of the PERL jpegDisplay.pl script
to point to your file pathname of perl.
=head1 Input options.
-b Search base.
-d Debug mode. Display debug messages to stdout.
-D Distingushed Name for authenication purposes.
-h LDAP directory host computer.
-w Authenication password.
-a Attribute that will be incorporated into the search filter.
-v Data that will be incorporated into the search filter.
-V LDAP version of the LDAP directory.
Usage: jpegDisplay.pl -b <base> -h <host> -d <number> -D <DN> \
-w <password> -a <attribute> -v <data>
Inside the script is a opt hash that can be initialized to
default values that can elminate the need for many of the
input options on the command line.
-------------------------------------------------------------------

-------------------------------------------------------------------
=head1 INSTALLING THE SCRIPT
Install the jpegDisplay.pl script anywhere you wish, I suggest
/usr/local/bin/jpegDisplay.pl.
-------------------------------------------------------------------
Since the script is in PERL, feel free to modify it if it does not
meet your needs. This is one of the main reasons I did it in PERL.
If you make an addition to the code that you feel other individuals
could use let me know about it. I may incorporate your code
into my code.
