Keystone Configuration Options¶

[DEFAULT]

#
# From keystone
#

# Using this feature is *NOT* recommended. Instead, use the `keystone-manage
# bootstrap` command. The value of this option is treated as a "shared secret"
# that can be used to bootstrap Keystone through the API. This "token" does not
# represent a user (it has no identity), and carries no explicit authorization
# (it effectively bypasses most authorization checks). If set to `None`, the
# value is ignored and the `admin_token` middleware is effectively disabled.
# However, to completely disable `admin_token` in production (highly
# recommended, as it presents a security risk), remove
# `AdminTokenAuthMiddleware` (the `admin_token_auth` filter) from your paste
# application pipelines (for example, in `keystone-paste.ini`). (string value)
#admin_token = <None>

# The base public endpoint URL for Keystone that is advertised to clients
# (NOTE: this does NOT affect how Keystone listens for connections). Defaults
# to the base host URL of the request. For example, if keystone receives a
# request to `http://server:5000/v3/users`, then this will option will be
# automatically treated as `http://server:5000`. You should only need to set
# option if either the value of the base URL contains a path that keystone does
# not automatically infer (`/prefix/v3`), or if the endpoint should be found on
# a different host. (uri value)
#public_endpoint = <None>

# The base admin endpoint URL for Keystone that is advertised to clients (NOTE:
# this does NOT affect how Keystone listens for connections). Defaults to the
# base host URL of the request. For example, if keystone receives a request to
# `http://server:35357/v3/users`, then this will option will be automatically
# treated as `http://server:35357`. You should only need to set option if
# either the value of the base URL contains a path that keystone does not
# automatically infer (`/prefix/v3`), or if the endpoint should be found on a
# different host. (uri value)
#admin_endpoint = <None>

# Maximum depth of the project hierarchy, excluding the project acting as a
# domain at the top of the hierarchy. WARNING: Setting it to a large value may
# adversely impact performance. (integer value)
#max_project_tree_depth = 5

# Limit the sizes of user & project ID/names. (integer value)
#max_param_size = 64

# Similar to `[DEFAULT] max_param_size`, but provides an exception for token
# values. With Fernet tokens, this can be set as low as 255. With UUID tokens,
# this should be set to 32). (integer value)
#max_token_size = 255

# Similar to the `[DEFAULT] member_role_name` option, this represents the
# default role ID used to associate users with their default projects in the v2
# API. This will be used as the explicit role where one is not specified by the
# v2 API. You do not need to set this value unless you want keystone to use an
# existing role with a different ID, other than the arbitrarily defined
# `_member_` role (in which case, you should set `[DEFAULT] member_role_name`
# as well). (string value)
#member_role_id = 9fe2ff9ee4384b1894a90878d3e92bab

# This is the role name used in combination with the `[DEFAULT] member_role_id`
# option; see that option for more detail. You do not need to set this option
# unless you want keystone to use an existing role (in which case, you should
# set `[DEFAULT] member_role_id` as well). (string value)
#member_role_name = _member_

# The value passed as the keyword "rounds" to passlib's encrypt method. This
# option represents a trade off between security and performance. Higher values
# lead to slower performance, but higher security. Changing this option will
# only affect newly created passwords as existing password hashes already have
# a fixed number of rounds applied, so it is safe to tune this option in a
# running cluster. For more information, see
# https://pythonhosted.org/passlib/password_hash_api.html#choosing-the-right-
# rounds-value (integer value)
# Minimum value: 1000
# Maximum value: 100000
#crypt_strength = 10000

# The maximum number of entities that will be returned in a collection. This
# global limit may be then overridden for a specific driver, by specifying a
# list_limit in the appropriate section (for example, `[assignment]`). No limit
# is set by default. In larger deployments, it is recommended that you set this
# to a reasonable number to prevent operations like listing all users and
# projects from placing an unnecessary load on the system. (integer value)
#list_limit = <None>

# If set to true, strict password length checking is performed for password
# manipulation. If a password exceeds the maximum length, the operation will
# fail with an HTTP 403 Forbidden error. If set to false, passwords are
# automatically truncated to the maximum length. (boolean value)
#strict_password_check = false

# DEPRECATED: The HTTP header used to determine the scheme for the original
# request, even if it was removed by an SSL terminating proxy. (string value)
# This option is deprecated for removal since N.
# Its value may be silently ignored in the future.
# Reason: This option has been deprecated in the N release and will be removed
# in the P release. Use oslo.middleware.http_proxy_to_wsgi configuration
# instead.

# If set to true, then the server will return information in HTTP responses
# that may allow an unauthenticated or authenticated user to get more
# information than normal, such as additional details about why authentication
# failed. This may be useful for debugging but is insecure. (boolean value)
#insecure_debug = false

# Default `publisher_id` for outgoing notifications. If left undefined,
# Keystone will default to using the server's host name. (string value)
#default_publisher_id = <None>

# Define the notification format for identity service events. A `basic`
# notification only has information about the resource being operated on. A
# `cadf` notification has the same information, as well as information about
# the initiator of the event. The `cadf` option is entirely backwards
# compatible with the `basic` option, but is fully CADF-compliant, and is
# recommended for auditing use cases. (string value)
# Allowed values: basic, cadf
#notification_format = cadf

# You can reduce the number of notifications keystone emits by explicitly
# opting out. Keystone will not emit notifications that match the patterns
# expressed in this list. Values are expected to be in the form of
# `identity.<resource_type>.<operation>`. By default, all notifications related
# to authentication are automatically suppressed. This field can be set
# multiple times in order to opt-out of multiple notification topics. For
# example, the following suppresses notifications describing user creation or
# successful authentication events: notification_opt_out=identity.user.create
# notification_opt_out=identity.authenticate.success (multi valued)
#notification_opt_out = identity.authenticate.success
#notification_opt_out = identity.authenticate.pending
#notification_opt_out = identity.authenticate.failed
