Keystone Configuration OptionsΒΆ

The following is a sample keystone configuration for adaptation and use. It is auto-generated from keystone when this documentation is built, so if you are having issues with an option, please compare your version of keystone with the version of this documentation.

The sample configuration can also be viewed in file form.

[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.
#secure_proxy_ssl_header = HTTP_X_FORWARDED_PROTO

# 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
