NM with VPN using multiple authentication modes

[Ramu <rpanayappan novell com>]

Hi list,

Was perusing the latest HEAD for integrating a VPN service with NM,
Noticed that as of now, there is just a provision of spawning one
auth-dialog for getting authentication credentials. 

But has the list explored the possibilities of having different modes of
authentication while connecting to a VPN gateway (For instance
authenticating with cisco using certificate mode and/or by using Group
authentication) ? 

In that case one may require to have provision to provide multiple
auth-dialog boxes in nm-<vpnname>-service.name and to spawn an
appropriate auth-dialog depending on the authentication method chosen.

Any thoughts?
