Error description
When using an IBM MQ v8 server and IBM MQ v8 Java or JMS client, if PasswordProtection attribute under the qm.ini Channels stanza is set to 'always' and USER_AUTHENTICATION_MQCSP is not set or specifically set to false (compatibility mode), the connection is authenticated and allowed. As PasswordProtection=always, we would expect the connection to fail in the same way that a pre-v8 client would.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users of the PasswordProtection attribute under the qm.ini Channels stanza may be affected by this issue. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: An IBM MQ v8 JMS client is able to connect to an IBM MQ v8 queue manager if the PasswordProtection attribute under the qm.ini Channels stanza is set to 'always', and the USER_AUTHENTICATION_MQCSP connection property is either unset, or set to false. This behaviour is not expected since the default behaviour for an IBM MQ v8 JMS client is to send user identifiers and passwords in plain text, unless USER_AUTHENTICATION_MQCSP is set to true. Setting PasswordProtection=always should prohibit the connection from succeeding unless either SSL/TLS is being used, or MQCSP password protection is enabled.
Problem conclusion
The code has been modified so that connections from IBM MQ v8 JMS client connections are rejected if the following are true: 1. PasswordProtection=always in qm.ini AND 2. The client has provided an MQCD password and userid AND 3. SSL/TLS is not being used AND 4. The queue manager has not seen an MQCSP flow from the client --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.5 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
