Friends,

How does LDAP and RADIUS differ? I've been hearing from a lot of people that their router supports RADIUS Authentication? Is LDAP and radius the same? Here's what I really want to have:

1.) Client workstations have MS Outlook installed and I want to have a centralized address book so that if I add one entry on the server, the address will therefore be reflected on the clients' PCs.
2.) I want to setup an authentication for Wireless users wherein they will need to be authenticated by the server. Currently, I use MAC filtering on IPCop. I will need to provide them Blue Access for them to be able to access the internet.

If LDAP and RADIUS is not the right technology, I hope someone can give me a hand on this. Thanks.

ldap and radius are just totally seperate thigns, nothing in common. ldap is a disrectory of users while radius is an authentication protocol for network connectivity and other forms of authentication. for your points 1) is for ldap and 2) could be the same ldap back end connected via a radius server.

Okay. How about Active Directory? I mean which is better LDAP or Active Directory?

active directory is a microsoft-ized version of ldap plus other junk. depends what you want to get out of it...

Okay. So, do you know a website which can teach me how to build a LDAP? I tried downloading the LDAP Documentations from the TLDP but it's just too complicated for me. ANy other website with tutorials on LDAP for newbies?
