Connecting to IBM MQ Docker Image Without Credentials

[x80486]

I'm setting up a local environment using Docker Compose with the IBM MQ container image (icr.io/ibm-messaging/mq:9.4.0.11-r3). My goal is to connect to the broker without specifying any username or password, similar to the setup for higher environments.

I've read that setting the MQSNOAUT environment variable to yes should allow this, but after I define it in the Docker Compose manifest, I'm unable to connect anymore, with or without credentials:

2025-07-21T03:44:12.748Z AMQ9776E: Channel was blocked by userid [CommentInsert1(DEV.APP.SVRCONN), CommentInsert2(172.18.0.1), CommentInsert3(MCAUSER(x80486) CLNTUSER(x80486) ADDRESS(_gateway))]
2025-07-21T03:44:12.749Z AMQ9999E: Channel 'DEV.APP.SVRCONN' to host '172.18.0.1' ended abnormally. [CommentInsert1(DEV.APP.SVRCONN), CommentInsert2(1018), CommentInsert3(172.18.0.1)]

I've also tried removing the mqAdminPassword and mqAppPassword secrets, but that leads me to the usual:

2025-07-21T03:46:41.735Z AMQ9791E: The client application did not supply a user ID and password. [CommentInsert1(node), CommentInsert2(_gateway (172.18.0.1)), CommentInsert3(MCAUSER(app) CLNTUSER(x80486) ADDRESS(_gateway))]
2025-07-21T03:46:41.735Z AMQ9999E: Channel 'DEV.APP.SVRCONN' to host '172.18.0.1' ended abnormally. [CommentInsert1(DEV.APP.SVRCONN), CommentInsert2(1023), CommentInsert3(172.18.0.1)]

The only setup that works is using the app username with the corresponding password I assign to it using the mqAppPassword secret.

I would appreciate any guidance on how to achieve this.
