```
export MINIO_IDENTITY_TLS_ENABLE=on
```

## Example

MinIO exposes a custom S3 STS API endpoint as `Action=AssumeRoleWithCertificate`. A client has to send an HTTP `POST` request to `https://<host>:<port>?Action=AssumeRoleWithCertificate&Version=2011-06-15`. Since the authentication and authorization happens via X.509 certificates the client has to send the request over **TLS** and has to provide
a client certificate.

	return ok
}

// Verify request has AWS PreSign Version '2'.
func isRequestPresignedSignatureV2(r *http.Request) bool {
	_, ok := r.Form[xhttp.AmzAccessKeyID]
	return ok
}

// Verify if request has AWS Post policy Signature Version '4'.
func isRequestPostPolicySignatureV4(r *http.Request) bool {
	mediaType, _, err := mime.ParseMediaType(r.Header.Get(xhttp.ContentType))
	if err != nil {
		return false
	}

## REST API call to plugin

To verify the custom token presented in the `AssumeRoleWithCustomToken` API, MinIO makes a POST request to the configured identity management plugin endpoint and expects a response with some details as shown below:

### Request `POST` to plugin endpoint

Query parameters:

| Parameter Name | Value Type | Purpose                                                                 |

	if ok {
		return rt
	}
	return nil
}

// Returns a minio-go Client configured to access remote host described by destDNSRecord
// Applicable only in a federated deployment
var getRemoteInstanceClient = func(r *http.Request, host string) (*miniogo.Core, error) {
	cred := getReqAccessCred(r, globalSite.Region)
	// In a federated deployment, all the instances share config files

	if resp.StatusCode == http.StatusOK {
		return respStr, nil
	}

	return respStr, fmt.Errorf("SUBNET request failed with code %d and error: %s", resp.StatusCode, respStr)
}

// Post submit 'payload' to specified URL
func (c Config) Post(reqURL string, payload interface{}) (string, error) {
	if !c.Registered() {
		return "", errors.New("Deployment is not registered with SUBNET. Please register the deployment via 'mc license register ALIAS'")

	},
	ErrMalformedPOSTRequest: {
		Code:           "MalformedPOSTRequest",
		Description:    "The body of your POST request is not well-formed multipart/form-data.",
		HTTPStatusCode: http.StatusBadRequest,
	},
	ErrPOSTFileRequired: {
		Code:           "InvalidArgument",
		Description:    "POST requires exactly one file upload per request.",
		HTTPStatusCode: http.StatusBadRequest,
	},
	ErrSignatureVersionNotSupported: {
