### 3. Configure `mc` and create another user user1 with attached policy user1policy

```
mc alias set myminio-admin1 http://localhost:9000 admin1 admin123 --api s3v4

mc admin user add myminio-admin1 user1 user123
mc admin policy attach myminio-admin1 user1policy ~/user1policy.json
mc admin policy attach myminio-admin1 user1policy --user=user1
```

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

### 3. Create a new group

```
mc admin group add myminio newgroup newuser
```

Once the group is successfully created you can now apply the `getonly` policy for this group.

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

### 4. Disable user

Disable user `newuser`.

#### Secure Erasure and Locking

The MinIO server requires an available KMS to en/decrypt SSE-S3 encrypted objects. Therefore it is possible to erase or lock some or all encrypted objects. For example in case of a detected attack or other emergency situations the following actions can be taken:

```
 mc ilm add --expiry-days 365 --transition-days 45 --storage-class "AZURETIER" myminio/srcbucket
```

Note: In the case of S3, it is possible to create a tier from MinIO running in EC2 to S3 using AWS role attached to EC2 as credentials instead of accesskey/secretkey:

```
mc admin tier add s3 source S3TIER --bucket s3bucket --prefix testprefix/ --use-aws-role
```
