Hi, I have configured freeradius server to authenticate & authorize user with the supplied username and password against active directory. Till this stage; The user can be authenticated and authorized successfully with credentials provided. For this purpose; user is just authenticated and authorized depending upon the filter of LDAP module which I have set. My LDAP module filter configuration is as: filter = "(sAMAccountName=%{%{Stripped-User-Name}:-%{User-Name}})" But Now, I want to go deep on authenticating and authorizing user to allow or reject VPN or Wifi access, etc. For this purpose I have created extension attribute in Active directory and has assigned the value as "VPN" , "Wifi", etc..... Now my question is: How can I set the filter in Ldap module of FreeRadius to just allow the user belonging to VPN or wifi ? Should I need to add the extension attribute filter to the above mentioned filter? OR should I need to define 2 filters: the above one and another for extension attribute? I tried defining 2 filters separately; it didn't work. I know some people use the concept of "Group" for this purpose. In my case, I can't use Group. I just have to authenticate and authorize user just using Active Directory attribute. I don't know whether this is way to do or not. Any idea would be really helpful. This forum has really helped a lot to the beginner like me to reach till this stage.
