# How to enable ADS RDS IAM Auth on postgresql

Set the environment variables

```Commandline
  DB_USER_PASSWORD: "dummy"
  DB_PARAMS: "awsRegion=eu-west-1&allowPublicKeyRetrieval=true&sslmode=require&serverTimezone=UTC"
```

Either through helm (if deployed in kubernetes) or as env vars.

{% note %}

The `DB_USER_PASSWORD` is still required and cannot be empty. Set it to a random/dummy string.
