trouble is, AD doesn't know my real ip. It shows my username, Radius server
IP and system name when searching for details.

One thing you could always do is use the post-auth function of the ldap
module to write the last ip address used into another ldap attribute.

It's not exactly the same as passing it in the auth. But may achieve the
same outcome.

I however would use the linelog module and log the event that way rather
than writing it into AD.
