[leshan-dev] DTLS security error in leshan client server testing

[Kailash Kumar <chaudhary.kailash10@xxxxxxxxx>]

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-

Device Registration (Success? FORBIDDEN)

        Device Registration Error: 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.
