## Managing User/Group Access Policy

Access policies may be associated by their name with a group or user directly. Access policies are first defined on the MinIO server using IAM policy JSON syntax. To define a new policy, you can use the [AWS policy generator](https://awspolicygen.s3.amazonaws.com/policygen.html). Copy the policy into a text file `mypolicy.json` and issue the command like so:

```sh

	// try this server to generate a new token.

	type healResp struct {
		respBytes []byte
		apiErr    APIError
		errBody   string
	}

	// Define a closure to start sending whitespace to client
	// after 10s unless a response item comes in
	keepConnLive := func(w http.ResponseWriter, r *http.Request, respCh chan healResp) {
		ticker := time.NewTicker(time.Second * 10)

	// accordingly. Client receives a HTTP error for invalid/unsupported
	// signatures.
	//
	// Validates all incoming requests to have a valid date header.
	setAuthMiddleware,
	// Redirect some pre-defined browser request paths to a static location
	// prefix.
	setBrowserRedirectMiddleware,
	// Adds 'crossdomain.xml' policy middleware to serve legacy flash clients.
	setCrossDomainPolicyMiddleware,

	Notify BatchJobNotification `yaml:"notify" json:"notify"`
	Retry  BatchJobRetry        `yaml:"retry" json:"retry"`
}
