MSM 720 User session persistence

[dimmyk]

Hello,

We experience an issue which is as follows:

We use HP MSM 720 Access Controller, to handle Wireless Clients as well as Ingress(Cabled) Clients.

We also implement External Radius Authentication(Controller acts as a NAS).

Everything works fine except this:

If the Controller lose the connection with the radius server and the user perform a logout(or the idle timeout attribute is being reached) the controller logs out the user without notify tha radius server(even when the connectivity re-established).

The same condition happens when a abnornal reboot happen to the controller:

When the Controller power up it "does not remember" the active user sessions.

So in both conditions, when a user tries to reconnect fails(due to max concurrent sessions set to one).The workaround is to manually remove the users from the Radius server.

Does anybody faced the same issue?any advice?

Thanks,

Dimitris
