Disabling allowConnectionsWithoutCertificates when using requireTLS in MongoDB Community Operator (v0.13.0)

[kanyi47]

What did you do to encounter the bug?
Hi,
I'm not sure if this is a bug, but I had to post it here. I can't figure it out or find any helpful information.
I’m deploying a MongoDB ReplicaSet using the MongoDB Community Operator v0.13.0 (Helm chart). I want to enforce mutual TLS so that clients must present a valid certificate signed by my CA.

My CR looks like this (simplified):

apiVersion: mongodbcommunity.mongodb.com/v1
kind: MongoDBCommunity
metadata:
  name: mongodb
  namespace: mongodb
spec:
  members: 3
  type: ReplicaSet
  version: "7.0.7"

  security:
    tls:
      enabled: true
      certificateKeySecretRef:
        name: mongodb-server-tls
      caConfigMapRef:
        name: mongodb-ca

  additionalMongodConfig:
    net:
      tls:
        mode: requireTLS
        allowConnectionsWithoutCertificates: false

What did you expect?
I expected allowConnectionsWithoutCertificates to be set to false inside mongod.conf, but instead it's defaulting to true

port: 27017,
      tls: {
        CAFile: '/var/lib/tls/ca/longhash.pem',
        allowConnectionsWithoutCertificates: true,
        certificateKeyFile: '/var/lib/tls/server/longhash.pem',
        mode: 'requireTLS'
      }

What happened instead?
allowConnectionsWithoutCertificates defaults to true, and I can connect to MongoDB by setting tls=true but not needing to provide the certificates. My target is allowing only clients that provide certificate to connect.

Operator Information
Kubernetes-mongodb-operator version 0.13.0
Mongodb community version 7.0.7
kubernetes version 1.33.2

Additional context
I can confirm that both mongodb-operator and mongodb community pods are running smoothly without any restarts.
