Now you have successfully configured Dex IdP with MinIO.

> NOTE: Dex supports groups with external connectors so you can use `groups` as policy claim instead of `name`.

```
export MINIO_IDENTITY_OPENID_CLAIM_NAME=groups
```

and add relevant policies on MinIO using `mc admin policy create myminio/ <group_name> group-access.json`
