Geert,
        Here are the RADIUS attributes that need to be enabled:

[64] Tunnel-Type
[65] Tunnel-Medium-Type
[81] Tunnel-Private-Group-ID

        If you are using Cisco ACS, you will need to enable the above
RADIUS attributes under "Interface Configuration --> RADIUS (IETF)".
You will see the option to enable them on a single user or group basis.
Once these are enabled, go to the particular user or group and for
Tunnel-Type Tag1 select "VLAN" from the dropdown menu. For
Tunnel-Medium-Type Tag1 select "802" from the dropdown menu. Lastly for
Tunnel-Private-Group-ID Tag1 type in the VLAN name. As a side note, the
VLAN name is case sensitive.

        Be sure to enable "aaa authorization network default group
radius" to allow the VLAN to be dynamically assigned.
