Re: [leshan-dev] DTLS security error in leshan client server testing
Hi,
I am still stuck at the same issue as mentioned in the earlier post. I tried using Scandium-1.0.0-M4 but then it shows DTLSConnector as deprecated. 
Moreover, I get from the source code that the response code 'FORBIDDEN' comes when 'The End-point Client Name results in a duplicate entry on the LWM2M Server'  but this does not seem the case for me. 

Any help on this is highly appreciated.

Hi,
I am trying to test UDP channel security between leshan-standalone server and LeshanClientExample. 
I tried both PSK mode and RPK mode separately by modifying both leshan-standalone and LeshanClientExample accordingly with help of SecurityTest and SecureIntegrationTestHelper classes. In both cases, client shows similar messages like the following-

Jun 11, 2015 2:45:21 PM org.eclipse.californium.scandium.dtls.Handshaker processMessageNext

Device Registration (Success? FORBIDDEN)

If you're having issues connecting to the LWM2M endpoint, try using the DTLS port instead.

and server console shows the following messages in RPK and PSK mode-

RPK Mode-
Jun 11, 2015 2:45:20 PM org.eclipse.californium.scandium.DTLSConnector receiveNext
INFO: Created new session as server with peer: /127.0.0.1:59787

PSK Mode-
INFO: Client /127.0.0.1:49739 used PSK identity : Client_identity

Could anyone please tell why the client is not able to register with the server? I am using Scandium-1.0.0-M3 library.

Thanks in Advance.
