DHCP Address Assignment

I have Winserver 2003 with Funk 802.1x Enterprise Edition and an Aruba
wireless LAN switch. Before adding the 802.1x authenication server I was
getting the DHCP address from the Win2003 server. Now I have set up the
802.1x server to send back a framed IP address to the switch which should
assign the client the appropriate address. What is happening is that the
client address is still coming from the original address pool and not from
the series defined by the 802.1x server. The 802.1x server logs show that
correct address is sent back to switch, but switch doesn't seem to send it
it to client. Any thoughts about is happening.
Thank you,
