### 6. Change user or group policy

Change the policy for user `newuser` to `putonly` canned policy.

```
mc admin policy attach myminio putonly --user=newuser
```

Change the policy for group `newgroup` to `putonly` canned policy.

```
mc admin policy attach myminio putonly --group=newgroup
```

### 7. List all users or groups
