Ken Giusti updated PROTON-735:
------------------------------
Description:
Using the current SASL api, an application has to poll the pn_sasl_t object's
state (pn_sasl_state()) until a terminal state is reached (STATE_PASS/FAIL).
Once the terminal state is reached, the outcome can be queried via
pn_sasl_outcome.
Unfortunately, when the sasl client receives an authentication failure outcome
from the sasl server, the sasl layer returns PN_ERR from its input processing
code. This causes the pn_transport_push() to return a generic error.
>From the application's point of view, this effectively results in the
>transport failing *before* the sasl terminal state has been reached. The
>application will interpret this event as a generic input failure on the
>transport - not the authentication failure it actually was.
