      #   # - {username_attribute} is a placeholder replaced by what is configured in `username_attribute`.

      #
      # With this backend, the users database is stored in a file

      # more than one instance. The options under 'password' have sane
      # defaults, and as it has security implications it is highly recommended
      # you leave the default values. Before considering changing these settings

    # Access Control

    #

    # Access control is a list of rules defining the authorizations applied for one

    # resource to users or group of users.

    #

    # If 'access_control' is not defined, ACL rules are disabled and the 'bypass'

    # rule is applied, i.e., access is allowed to anyone. Otherwise restrictions follow

    # the rules defined.

    #

    # Note: One can use the wildcard * to match any subdomain.

    # It must stand at the beginning of the pattern. (example: *.mydomain.com)

    #

    # Note: You must put patterns containing wildcards between simple quotes for the YAML

    # to be syntactically correct.

    #

    # Definition: A 'rule' is an object with the following keys: 'domain', 'subject',

    # 'policy' and 'resources'.

    #

    # - 'domain' defines which domain or set of domains the rule applies to.

    #

    # - 'subject' defines the subject to apply authorizations to. This parameter is

    #    optional and matching any user if not provided. If provided, the parameter

    #    represents either a user or a group. It should be of the form 'user:<username>'

    #    or 'group:<groupname>'.

    #

    # - 'policy' is the policy to apply to resources. It must be either 'bypass',

    #   'one_factor', 'two_factor' or 'deny'.

    #

    # - 'resources' is a list of regular expressions that matches a set of resources to

    #    apply the policy to. This parameter is optional and matches any resource if not

    #    provided.

    #

    # Note: the order of the rules is important. The first policy matching

    # (domain, resource, subject) applies.

    access_control:
      # Default policy can either be 'bypass', 'one_factor', 'two_factor' or 'deny'.
      # It is the policy applied to any resource if there is no policy to be applied
      # to the user.
