iOS config and L2TP secret missing from user portal when using RADIUS

Hi,

ASL 8.203.

I'm currently testing RADIUS authentication for L2TP VPN's. Until now I haven't much success (see my other post). Something else I noticed and what presumably stops me from using RADIUS authentication is that once I enable RADIUS authentication on the L2TP VPN, the iOS configuration download and L2TP shared secret key is missing from the user portal's remote access page. When I enable local authentication the 2 items reappear again after a refresh of the Remote Access page.

Any idea what's the reason for this?
