# Access Management Plugin Guide [![Slack](https://slack.minio.io/slack?type=svg)](https://slack.minio.io)

MinIO now includes support for using an Access Management Plugin. This is to allow object storage access control to be managed externally via a webhook.

```

### MinIO Custom Access and Secret Keys using Docker secrets

To override MinIO's auto-generated keys, you may pass secret and access keys explicitly by creating access and secret keys as [Docker secrets](https://docs.docker.com/engine/swarm/secrets/). MinIO server also allows regular strings as access and secret keys.

```
echo "AKIAIOSFODNN7EXAMPLE" | docker secret create access_key -

ENV MINIO_ACCESS_KEY_FILE=access_key \
    MINIO_SECRET_KEY_FILE=secret_key \
    MINIO_ROOT_USER_FILE=access_key \
    MINIO_ROOT_PASSWORD_FILE=secret_key \
    MINIO_KMS_SECRET_KEY_FILE=kms_master_key \

var errVolumeNotEmpty = StorageErr("volume is not empty")

// errVolumeAccessDenied - cannot access volume, insufficient permissions.
var errVolumeAccessDenied = StorageErr("volume access denied")

// errFileAccessDenied - cannot access file, insufficient permissions.
var errFileAccessDenied = StorageErr("file access denied")

// errFileCorrupt - file has an unexpected size, or is not readable

		defer updateOSMetrics(osMetricOpenFileR, name)(err)
	}
	return os.OpenFile(name, flag, perm)
}

// Access captures time taken to call syscall.Access()
// on windows, plan9 and solaris syscall.Access uses
// os.Lstat()
func Access(name string) (err error) {
	defer updateOSMetrics(osMetricAccess, name)(err)
	return access(name)
}

// Open captures time taken to call os.Open
func Open(name string) (f *os.File, err error) {

	for _, b := range accInfo.Buckets {
		gotBuckets.Add(b.Name)
		if !(b.Access.Read && b.Access.Write) {
			c.Fatalf("root user should have read and write access to bucket: %v", b.Name)
		}
	}
	shouldHaveBuckets := set.CreateStringSet(bucket2, bucket)
	if !gotBuckets.Equals(shouldHaveBuckets) {
		c.Fatalf("root user should have access to all buckets")
	}

	// This must fail.

Example: Limit a MinIO cluster to accept at max 1600 simultaneous S3 API requests across all nodes of the cluster.

```sh
export MINIO_API_REQUESTS_MAX=1600
export MINIO_ROOT_USER=your-access-key
export MINIO_ROOT_PASSWORD=your-secret-key
minio server http://server{1...8}/mnt/hdd{1...16}
```

or

```sh

  ## https://kubernetes.io/docs/tasks/access-application-cluster/configure-cloud-provider-firewall/#restrict-access-for-loadbalancer-service
  ##
  #loadBalancerSourceRanges:
  #   - 10.10.10.0/24
  loadBalancerSourceRanges: []

  ## service.externalTrafficPolicy minio service external traffic policy

MINIO_IDENTITY_OPENID_COMMENT               (sentence)  optionally add a comment to this setting
```

### Access Control Configuration Variables

Either `MINIO_IDENTITY_OPENID_ROLE_POLICY` (recommended) or `MINIO_IDENTITY_OPENID_CLAIM_NAME` must be specified but not both. See the section Access Control Policies to understand the differences between the two.
