---------------------------------
Summary: SASL authentication failures appear as I/O failures
Key: PROTON-735
URL: https://issues.apache.org/jira/browse/PROTON-735
Project: Qpid Proton
Issue Type: Bug
Components: proton-c
Affects Versions: 0.8
Reporter: Ken Giusti
Fix For: 0.9
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.
