Error description

  • Unable to connect to local queue manager with AzureAD domain
    user account.
    
    An AzureAD domain user (in the mqm group) executing runmqsc.exe
    results in "AMQ8135: Not authorized." message at command prompt.
    
    FFST files are produced with Errorcode: MQRC_NOT_AUTHORIZED and
    (for example) ProbeID: PU821050 with
    MQM Function Stack:
    fcxControlProcessMain
    fmxInitialize
    fmiSubscribeStreams
    fmiMakeStreamSupportedSubscription
    
    Queue manager error logs show AMQ8075 errors with the text:
    "AMQ8075: Authorization failed because the SID for entity
    '<first 12 characters of username>' cannot
    be obtained."
    

Local fix

  • Use a locally-defined account to connect to the queue manager
