Domain Stripping Hack
This tech tip explains how to enable a feature which
will allow a Layer 2 Forwarding (L2F) Home Gateway or Layer 2 Tunneling
Protocol (L2TP) Network Server to strip the domain name off of an
incoming Virtual Private Data Network (VPDN) user.
While Cisco IOS software doesn't have a formal
feature that will allow a L2F/L2TP HGW/LNS to strip the domain name off
of an incoming VPDN user, there is a hack based on directed-requests
that does the same thing. When doing directed-requests with
TACACS+/RADIUS, the domain name is stripped off, so we can effectively
"trick" the router into stripping the
domain name by forcing a directed request.
