Alex Rudyy commented on QPID-7282:
----------------------------------
Authentication providers storing credentials in broker configuration (Plain,
SCRAM-SHA-256, SCRAM-SHA-1) are not affected by the issue. Only authentication
providers of types PlainPasswordFile and Simple are affected
> Java Broker should always send server-final message (if required) to the
> client on succesful SASL negotiation

> Key: QPID-7282
> URL: https://issues.apache.org/jira/browse/QPID-7282
> Project: Qpid
> Issue Type: Bug
> Components: Broker-J
> Affects Versions: 0.30, 0.32, qpid-java-6.0, qpid-java-6.0.1,
> qpid-java-6.0.2, qpid-java-6.0.3, qpid-java-6.1
> Reporter: Alex Rudyy
> Priority: Major
> Fix For: qpid-java-6.0.4, qpid-java-6.1
>
>
> On Scram Sha SASL negotiation Broker does not send server-final challenge
> (ServerSignature) with the following authentication providers:
> * Simple (SimpleAuthenticationManager)
> * PlainPasswordFile (PlainPasswordDatabaseAuthenticationManager)
> The sasl negotiation for Scram Sha SASL mechanisms should always include
> sending of server-final message in order to give a chance to verify server
> signature on a client as per [RFC
> 5802|https://tools.ietf.org/html/rfc5802#page-7]
> {quote}
> The client then authenticates the server by computing the
> ServerSignature and comparing it to the value sent by the server. If
> the two are different, the client MUST consider the authentication
> exchange to be unsuccessful, and it might have to drop the
> connection.
> {quote}
> We need to change all existing Authentication Provider to support sending of
> final message
