# This script reads the file /etc/passwd and grabs the userid values and
# name values of each user. The script then attempts to create a ldif file
# for the ldap server to have fed into the database.
#
# Some things to note:
#
#	- the root dn of the ldif file is set by the initial variables
#         set by the user. These are hardcoded in the script and the
#	  beginings of the ldif file are started with this information.
#
# 	- The usual system type entries in the passwd file are ignored.
#	  It is unlikely however possible that the script may generate
#	  some entries that are not wanted due to new entries in the 
# 	  passwd file representing new services offered by a more recent
# 	  version of GNU/Linux OS. This is treatable, via the modification
#	  of a couple lines of code.
