title: ibmcom/mq. "useradd: group 'mqm' does not exist" error for new image version
body: <p>Recently I was able to run my app with ibmcom/mq:9.1.3.0-r3 and following Dockerfile definition:</p>
  <pre><code>FROM ibmcom/mq:9.1.3.0-r3
  ENV LICENSE accept
  ENV MQ_QMGR_NAME QM_MY_APP
  USER root
  RUN usermod -a -G mqm admin 
  RUN usermod -a -G mqm root 
  RUN useradd -g mqm my_user_id
  ADD QueueManager /etc/mqm/myapp.mqsc
  USER mqm
  </code></pre>
  <p>But now ibmcom/mq:9.1.3.0-r3 is not available on Dockerhub. When I pull and run other available docker versions (like 9.2.0.0-r1 and up) it throws following error because of commands in Dockerfile:</p>
  <blockquote>
  <p>useradd: group 'mqm' does not exist</p>
  </blockquote>
  <p>I read the <a href="https://stackoverflow.com/questions/61601607/mq-custom-docker-image-mqm-group-not-found">MQ Custom Docker Image - MQM Group Not Found</a>, where the user &quot;chughts&quot; suggests to &quot;use htpasswd with bcrypt to create the users.&quot;</p>
  <p>Does anyone knows, how to use htpasswd to create the users in mq?
  Thanks a lot for Your support in advance!</p>
  <p>EDIT: I need to create an user via htpasswr for debug and local tests only. In production envirounment the qm's default user settings is used.</p>
