Rajith Attapattu commented on QPID-3415:
----------------------------------------
I would also want to test this patch with GSSAPI and EXTERNAL to ensure
everything works as expected.
We do have existing customers that rely on those two mechanisms. I'll try to
get the testing going asap.
> CRAM-MD5-HASHED not supported by 0-10 protocol (+ no suppport for custom SASL
> mechanisms).

> Key: QPID-3415
> URL: https://issues.apache.org/jira/browse/QPID-3415
> Project: Qpid
> Issue Type: Bug
> Components: Java Client
> Affects Versions: 0.10
> Reporter: Keith Wall
> Assignee: Rajith Attapattu
> Fix For: 0.13
>
>
> If the Java broker is configured to use the Base64MD5Password password
> database the Java client is unable to connect even if they use the sasl_mechs
> broker option in the connection URL (sasl_mechs='CRAM-MD5-HASHED').
> Instead the user sees:
> {code}
> org.apache.qpid.AMQException: Cannot connect to broker: Callback handler with
> support for AuthorizeCallback required
> {code}
> The user can work around the problem by passing the -Dqpid.amqp.version
> system property to the client, and selecting a protocol < 0-10.
> The problem is happening because on the 0-10 code path on the client, the
> SASL CallbackHandler in use is hardcoded to UsernamePasswordCallbackhandler
> (ClientDelegate), rather than using the facilities of CallbackHandlerRegistry
> (as does the 0-8 and 0-9* code paths). CRAM-MD5-HASHED requires the use of a
> different Callbackhandler.
> This also inhibits the use of custom SASL methods by the client.
