Cisco VPN :: PIX 515E VPN Client Static IPs?

I have my PIX 515E (8.0(4)24) configured for VPN access. In the VPN configuration, I am using an RA tunnel group configured to use Windows 2003 IAS to authenticate users against active directory based on group membership and using a local IP pool for address assignment. This all works fine. I got a request from a single user to have a static IP assigned from the pool. I read that one way you can do this is to get into the user properties in Active Directory for the user and in the dial-in tab tick the box for 'Assign a static IP address' to have it give the particular user a static address for VPN, but it does not work. What I would like the PIX to do is assign addresses from the local pool unless there is an address assignment configuration in RADIUS. Basically does the PIX honor the IP assigned via RADIUS even if the tunnel group is configured for a local IP pool or do I need to configure the tunnel group to use AAA address assingment for the AD dial-in config to work at all? Does the PIX functions this way? I configured the user in AD for this but it does not work. I also have the no vpn-addr-assign aaa command enabled in there which might be the whole issue. I will try to change this in the next window and see if it flies then. Just wanted to see if the PIX works this way or if I am way off here.
