# Authentication methods
#
# Authentication methods can be defined per subdomain.
# There are currently two available methods: "single_factor" and "two_factor"
#
# Note: by default a domain uses "two_factor" method.
#
# Note: 'per_subdomain_methods' is a dictionary where keys must be subdomains and
# values must be one of the two possible methods.
#
# Note: 'per_subdomain_methods' is optional.
#
# Note: authentication_methods is optional. If it is not set all sub-domains
# are protected by two factors.
authentication_methods:
  default_method: two_factor
  per_subdomain_methods:
    single_factor.example.com: single_factor

# Access Control
#
# Access control is a set of rules you can use to restrict user access to certain 
# resources.
# Any (apply to anyone), per-user or per-group rules can be defined.
#
# If 'access_control' is not defined, ACL rules are disabled and the `allow` default 
# policy 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 the pattern in simple quotes when using the wildcard for the YAML
# to be syntaxically correct.
#
# Definition: A `rule` is an object with the following keys: `domain`, `policy` 
# and `resources`.
# - `domain` defines which domain or set of domains the rule applies to.
# - `policy` is the policy to apply to resources. It must be either `allow` or `deny`.
# - `resources` is a list of regular expressions that matches a set of resources to 
# apply the policy to.
#
# Note: Rules follow an order of priority defined as follows:
# In each category (`any`, `groups`, `users`), the latest rules have the highest 
# priority. In other words, it means that if a given resource matches two rules in the
# same category, the latest one overrides the first one.
# Each category has also its own priority. That is, `users` has the highest priority, then
# `groups` and `any` has the lowest priority. It means if two rules in different categories
# match a given resource, the one in the category with the highest priority overrides the
# other one.
#
access_control:
  # Default policy can either be `allow` or `deny`.
  # It is the policy applied to any resource if it has not been overriden
  # in the `any`, `groups` or `users` category.
  default_policy: deny
  groups:
    admins:
      # All resources in all domains
      - domain: '*.example.com'
        policy: allow
      # Except mx2.mail.example.com (it restricts the first rule)
      #- domain: 'mx2.mail.example.com'
      #  policy: deny

  # User-based rules. The key is a user name and the value
  # is a list of rules.

    john:
      - domain: dev.example.com
        policy: allow

# Configuration of the authentication regulation mechanism.
#
# This mechanism prevents attackers from brute forcing the first factor.
# It bans the user if too many attempts are done in a short period of
# time.
regulation:
  # The number of failed login attempts before user is banned. 
  # Set it to 0 to disable regulation.
  max_retries: 3

  # The time range during which the user can attempt login before being banned.
  # The user is banned if the authenticaction failed `max_retries` times in a `find_time` seconds window. 
  find_time: 120

  # The length of time before a banned user can login again.
  ban_time: 300

# Default redirection URL
#
# If user tries to authenticate without any referer, Authelia
# does not know where to redirect the user to at the end of the
# authentication process.
# This parameter allows you to specify the default redirection
# URL Authelia will use in such a case.
#
# Note: this parameter is optional. If not provided, user won't
# be redirected upon successful authentication.
#default_redirection_url: https://authelia.example.domain
