# 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

# 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)

# 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
