Sorry to have to say it but I think you had Cisco at "not supported" on
this one. Also broken on this "feature" is MAC address filtering
combined with IP address filterning. It is not working in 4.5.0 and I
can't seem to even get an answer as to whether it is GOING to be fixed,
much less when. On further consideration, I guess that answers my
question after all, doesn't it? 

I will be curious to know your resolution because VPN SSO is the next
phase of my rollout here.
