1) You need to change any code that refers to Net::LDAP to Net::LDAPS
2) you obviously need to also have the Net::LDAPS perl module installed
(which means you also need Net::SSLeay, and IO::Socket::SSL as these are
dependancies)
3) you need to make sure the Net::LDAPS->new( ... ) call has the right
parameters for connecting to your secure LDAP server. most likely you
won't have to change anything...but you might need to provide a
certificate or something...check the Net::LDAPS doco.

We (Griffith Uni, with a little help from Lawrence uni and others) have
had 2 developers (and assistance of a dozen others for review etc) spend
the last 4 months completely re-writing/testing/implementing the netreg
code into what is known informally as "netreg2". It's massively more
"corporatized", and supports heaps more functions... including multiple
DHCP servers, DHCP failover, editing of the dhcpd.conf file via the web,
grouping of hosts, dynamic and static host registrations, database
back-end support, innumerable access controls based on function,
support-staff controlled registration/s etc etc.

It's current state is "alpha" code, but we "rolling it out" here , and
have "in production" 5 DHCP fail-over pairs (we have 5 campuses) ie 10
DHCPD servers (and one separate "registration" server that runs the
"dodgy" DNS, and web registration page/s), and we have about 20 class C
(ie /24) subnets that have been converted to this system. (more every
week). We'll have a couple of hundred /24 subnets and about 12-15,000
hosts by the time we are done rolling out. ;-)

I'd suggest having a look at our CVS source for http://www.sourceforge.net/projects/netreg

David

P.S. there are a number of bigish improvements that we've made in the last
week that aren't up in the CVS yet as we are still flushing the bugs out
of them, but they'll be there soon.
