802.1x authentication happens without an IP address. Only MAC addresses on used between the station and the access point. So there is no IP information to transfer. Once connected, the station may have a fixed IP, or hopefully use DHCP, but the authentication has long passed, and those transactions are outside of RADIUS. Dave.

Can Radius Server pass client ip details to Windows AD during ntlm authentication ?.
Here is the scenario, WirelessLanController is configured to provide access only after authenticating using Radius. Radius server is configured for WPA2 Enterprise with Active Directory integration using samba/winbind (ntlm_auth).
I can login to the wireless network using AD username and password. The trouble is, AD doesn't know my real ip. It shows my username, Radius server IP and system name when searching for details.
