Since MQ 9.1.5, we've made changes to allow running MQ under more strict security settings. These changes included the removal of the mqm UID and GID. Also, MQ is no longer authorized to check the passwords of Linux users, so you can no longer use the above technique to add users.

The recommendation for production use, is LDAP or mutual TLS. For the MQ Advanced for Developers image only, there is an unsupported MQ auth service which takes users from an htpasswd file. This isn't tested for general use, but you could perhaps update the code to use additional users that way if that's what you need.

Closing this because adding OS users to the image does not work when using the MQ unzippable installer, which this sample uses.
