APAR status

  • Closed as program error.

Error description

  • An inbound SSL/TLS enabled client connection to  the QMgr fails
    with AMQ9642 (rrcE_SSL_NO_REMOTE_CERT).  This indicates that
    there is no certificate being presented by the client although
    one is present in the hardware cryptographic keyring.  The
    certificate is labelled correctly as ibmwebspheremq+userid.
    
    GSKIT returns error 407: GSK_ERROR_BAD_KEYFILE_LABEL.
    
    For example, the below is seen in
    the AMQ.SSL.TRC file :
    Error: Not Found. Label =
    <token label>:<token label>:ibmwebspheremqmyuserid

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of IBM MQ with cryptographic hardware.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A coding error when building the certificate label to pass to
    MQ's cryptographic provider meant that it was possible for MQ to
    prepend the PKCS #11 token label to the certificate label twice
    before the certificate label was validated. This caused the
    validation to fail.
    

Problem conclusion

  • The MQ certificate management logic has been modified so that
    the token label is only appended once to the certificate label
    as expected.
