Re: Setting FreeRadius and Ldap. - Getting Educated Now

Ivan, 

Thanks for the url link to the missing documentation. Very helpful.
Ldap is not going to work for EAP.

Now I am facing a dilemma - deciding what WEP protocol to use based on
my test setup. After reading the 'sites' and 'modules' files it seems
that some  WEP or EAP protocols are weaker than others, some not
suggested for use.

Here's what my test router and machines can handle. 

Router can provide - WEP 40/128 shared key, WEP Personal, WEP Enterprise
Chiper: TKIP or AES

Workstation:WEP 40/128 shared key, Leap, Dynamic WEP, WPA  WPA2
Personal  Enterprise

Older Laptop: WEP 40/128 shared key, 802.1 Cisco LEAP or EAP FAST
--this may be the limiting machine.

I need to rely on list users experience for suggested paths to pursue?

Steven

Use WPA2 Enterprise (PEAP) on the workstation and LEAP for older laptop.
Server should support both in default configuration.

dont use WEP. ever.

surely you mean WPA personal and WPA enterprise (TKIP or AES)?


I would say WPA enterprise with AES. its the bext you can get currently
on your kit

 Older Laptop: WEP 40/128 shared key, 802.1 Cisco LEAP or EAP FAST
 --this may be the limiting machine.

the limiting factor here is most likely the software on the system - use
a different tool to control the wireless authentication

Thanks Alan,

WPA Enterprise with AES, I will do some more reading to understand the
benefits of AES.

As for the older laptop - I choose this unit because if represents
the oldest of technologies that will be accessing the network. This IBM
Thinkpad uses a Cisco (Calexico) internal wireless card using current
Windows XP (SP3) card drivers (from IBM / Lenovo). So unless there is a
better solution for controlling this wireless card I am stuck with
dealing with its offerings: WEP, Cisco Leap and EAP FAST.

TKIP is semi-broken, in that you can do ARP poisoning attacks without needing 
the PMK.

Were mandating WPA2-AES for this academic year.
