[TriLUG] LDAP vs AD vs NT domains vs eDirectory vs RHEL directoryserver

[OlsonE at aosa.army.mil]

well, if you were intending on staying with a windows machine for some
form of services, i'd highly recommend you migrate nt4 to windows 2003.
the path is fairly easy, and upgrade is minimal (depending on what nt4
services you were running). this would also preserve your clients, and
user names and passwords. if you're really not concerned about this,
then put in a win2k3 domain controller.

if you have any specific questions about nt4 > win2k3, you can contact
me off list if you like (or on list even). i rolled out a large scale
nt4 > win2k3 migration for the government (with 3 remote sites). 

user management is definitely a lot easier in win2k3 ad... and ad gives
you quite a few things you can do with your windows clients. i've heard
of people migrating off nt4 and using their linux server as a "domain
controller" so to speak ...but i personally haven't tried it in
production.

We have an old dying NT4 domain that we currently use only for user
authentication to gain access to network services.  We are long overdue
for an overhaul and I am looking for advice on which direction to go.
As I mentioned before currently we are using the NT4 domain for user and
Windows client authentication, our overall goal will be that all mail
(postfix,) linux systems and users, and other possible MS apps be able
to authenticate against this.
Here are my questions:
1.  What could be a drop in replacement for our current NT4 domain?
2.  What will give us AD type authentication/access and how easy or
difficult will it be to set up, ie is there anything as easy as the
click and add feature available in AD?
