Throws:

java.io.IOException

                               AuthCallbacks.GenericCallback<java.lang.Void> completeCb)

If the authentication was successful, BKException.Code.OK should be passed as the return code. Otherwise, another error code should be passed.

Parameters:

connection - an handle to the connection

completeCb - callback to be notified when authentication is complete.
