I am a Linux newbie and I need to install FreeRADIUS on my OES SLES 9 box.
We have some Wireless Access Points that are RADIUS aware and can use a
RADIUS server to authenticate.

My problem is that while reading the instructions for FreeRADIUS
installation it is said that I need an LDAP. And I have this much -> <-
understanding of LDAP. How do I install it, and test that it's working? And
then how do I test FreeRADIUS?

Does anyone have the Kindergarten version of these instructions?
