MAC/VLAN with HP Procurve

Hi all, Part 2 of my problems - has anyone got a radius server to hand out dynamic VLANs to an access point? I've got the following from various sites, but it doesn't seem to work (users file): 00-0e-35-31-5c-1b Auth-Type == Local,User-Password == "00-0e-35-31-5c-1b" Tunnel-Medium-Type = 802, Tunnel-Private-Group-ID = 20, Tunnel-Type = VLAN - this is meant to make the laptop with the given VLAN join to the network on vlan 20, but there is no sign of this working... any clues? cheers Jim Potter -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
