font-family:Arial'>I am trying to authenticate my network against <b><font
color=blue><span style='color:blue;font-weight:bold'>Windows 2003 Active
Directory</span></font></b>. With help from Ivan Kalik, I was able to use <b><font
color=blue><span style='color:blue;font-weight:bold'>NTLM</span></font></b> to
communicate with Windows 2003 server and authenticate EAP clients. On the EAP
side I am using <b><font color=blue><span style='color:blue;font-weight:bold'>PEAP</span></font></b>
since they are mostly windows XP clients and I don’t think there is
another choice (<font color=red><span style='color:red'>please correct me if I
am wrong</span></font>). However on the Radius server side, I seem to have
options. It seems that I can use <b><font color=blue><span style='color:blue;
font-weight:bold'>NTLM, Kerberos 5 or LDAP</span></font></b> to authenticate
with Windows Domain Controller. So my questions are: <o:p></o:p></span></font></p>

why?<o:p></o:p></span></font></p>

these days and I really appreciate your help! Now I am really a fan of
FreeRadius. I really want to learn it well and understand what it’s
capable of. I am a Cisco guy and I have some Linux experience but no
programming experience. Can any of you recommend me a book about how to use
FreeRadius? I think that will stop me asking stupid questions…<o:p></o:p></span></font></p>
