IT28807: .NET application cannot connect to queue manager if a user ID but no password is configured

APAR status

• Closed as program error.

Error description

• A MQ .NET application failed to connect to Queue Manager while
  sending userid without password. The .NET client reports a
  message similar to the following:
  
  Connecting to queue manager..Exception caught:
  System.NullReferenceException: Object reference not set to an
  instance of an object.
  At IBM.WMQ.MQQueueManager.Connect
  

Local fix

• Modify the application to either pass both the userid and the
  password, or neither.
  

Problem summary

  USERS AFFECTED:
  This issue affects MQ .NET applications which provide a user ID
  to the connect call but do not provide a password.
  
  
  Platforms affected:
  Windows
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A defect in the connect call logic meant that a null password
  value was not handled correctly if a user ID was set.

  case where a user ID is provided with a null password.
