What did you expect?
I want to set authenticationMechanisms to SCRAM-SHA-1

What happened instead?
The authenticationMechanisms is SCRAM-SHA-256:

Operator Information

• Operator Version
• MongoDB Image used

Kubernetes Cluster Information

• Distribution
• Version
• Image Registry location (quay, or an internal registry)

Additional context
Add any other context about the problem here.

If possible, please include:

• kubectl describe output
• yaml definitions for your objects
• log files for the operator and database pods

Hey @drivebyer,
I was also facing the same issue but I resolved it by adding

security:
    authentication:
      modes: ["SCRAM-SHA-1"]

It worked for me and changed the authentication mechanism

thanks @harshau007 , i would have a try.

It works. I set modes to ["SCRAM", "SCRAM-SHA-1"] to enable sha-256 && sha-1.
