### User authentication

It is possible to control access to cerebro through authentication.

At the moment, there are no roles/permission level, and either an user is able to access or not.

There are two methods of authentication:

  - Basic: username and password on the configuration file

  - LDAP: connect to an external provider for authentication

Example for basic:

```yaml

auth {

  type: basic

  settings: {

    username = "admin"

    password = "1234"

  }

}

```

Example for LDAP:

```yaml

auth {

  type: ldap

  settings: {

    url = "ldap://host:port"

    base-dn = "ou=active,ou=Employee"

    method  = "simple"

    user-domain = "domain.com"

  }

}

```
