APAR status
Closed as program error.
Error description
A username is provided by a client program connecting to the queue manager. This username is not valid according to the user/group repository in use. The username is eventually rejected. The rejection should happen much earlier in the internal processing being done on behalf of the SVRCONN channel, to make the MQ code consistent with the MQ design.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users of queue managers that serve clients. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A logic error meant that once a SVRCONN channel had determined that a connection would be rejected due to an authentication failure, additional validation were unnecessarily performed against this connection, instead of returning the authentication failure response to the client immediately.
Problem conclusion
The MQ code has been corrected. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.15 v9.0 LTS 9.0.0.10 v9.1 CD TBC. v9.1 LTS 9.1.0.6 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 ---------------------------------------------------------------
