freeradius with NTLM authentication

[Ramzi Abdallah]

I have configured
freeradius version 2.1.9 with mySQL backend and Active Directory integration
(NTLM) for the purpose of using it to authenticate users against firewall protected
policies. 



So far it’s all working. When
a user hits a firewall protected policy he is prompted to authenticate after which
the radius query the AD for the username and password. If the user credentials
are correct access is granted.

 

The bit that I cannot
figure out is how to let the Radius use NTLM to check if the user is already
logged in the domain controller and if so not to prompt him for his
username and password via the firewall captive portal.  Is that doable or I missed the idea behind the
Active Directory integration?

 

 

thank you

 

Ramzi
