This is not yet supported by the open source hostapd. However, I'm in
the process of merging in support for dynamic VLANs into hostapd from
Devicescape tree. This does not yet provide the exact functionality that
you are asking for here, but it provides the basics needed for
supporting dynamic selection of VLAN based on RADIUS server response.
The only needed addition would be to add a configuration option that
maps access rejects to a specific VLAN ID. This should be easy to add
once the core functionality for dynamic VLANs is merged in.
