APAR status

  • Closed as program error.

Error description

  • After disabling OCSP checking by setting 'ocsp.enable=off' in
    the keystore.conf file, and/or after disabling CRL CDP checking
    by setting 'crl.cdp=off' in the keystore.conf file, an MQ AMS
    application using the native interceptors fail to MQOPEN
    an AMS-protected queue with reason code 2063, which is
    MQRC_SECURITY_ERROR.
    

Local fix

  • You can work around the problem by adding an additional
    parameter in each case.  If you wish to disable OCSP, set both
    of these:
    .
        ocsp.enable=off
        ocsp.url=localhost
    .
    To disable CRL CDP checking, set both of these parameters in
    the keystore.conf file:
    .
        crl.cdp=off
        crl.ldap.host=localhost
    .
    .
     Restart the AMS application after making the change and OCSP
    and/or CRL CDP checking should be disabled for it.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of Advanced Message Security attempting to use crl.cdp
    or ocsp.enable without a configured host.
    
    This affects users of the native interceptors, which excludes
    Java applications, but includes MCA (channel) interception.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A logic error within the AMS interceptor caused an internal
    validation check for OCSP and CRL checking to incorrectly fail
    when OCSP and/or CRL checking was set to off with no hostname
    configured in the keystore.conf file.
    

Problem conclusion

  • The AMS interceptor logic has been corrected to address this
    issue. The fix must be applied to the installation from which
    the AMS interceptor code is obtained - in the client interceptor
    case, the is the client installation. In the MCA interception
    case, this is the queue manager installation.
