Netreg LDAP authentication addon.

These files are replacements for the ones that come with Netreg 1.2
They add LDAP authentication to Netreg in addition to the standard pop and ftp.
You will need the Net::LDAP module that is maintained by Graham Barr <gbarr@pobox.com>

For trouble with that module, please subscribe to their mailing list (perl-ldap-dev@lists.sourceforge.net).  I will only answer problems with my code.  

This code has been tested by me on NDS LDAP (v3 compliant).

The changes are as follows:
	- Added additional 'if' section to authenticate() (register.cgi.ldap), also did a 
	check to verify that user and password are not blank
	- Added LDAP variables to variables.pl.ldap 
		- Make sure you change the base 'o' there or it won't work.

Any questions, comments, praises, etc. are to be directed to grinnell@american.edu
