sql_pool_size
Type

integer

sql_pool_max_overflow
Type

integer

Default

10

# The maximum overflow size of the pool used by SQLAlchemy. When the number of checked-out connections reaches the size set in sql_pool_size, additional connections will be returned up to this limit. It follows then that the total number of simultaneous connections the pool will allow is sql_pool_size + sql_pool_max_overflow. Can be set to -1 to indicate no overflow limit, so no limit will be placed on the total number of concurrent connections. Comment out to allow SQLAlchemy to select the default.

keystone_authtoken

www_authenticate_uri
Type

string

Default

<None>

Complete “public” Identity API endpoint. This endpoint should not be an “admin” endpoint, as it should be accessible by all end users. Unauthenticated clients are redirected to this endpoint to authenticate. Although this endpoint should ideally be unversioned, client support in the wild varies. If you’re using a versioned v2 endpoint here, then this should not be the same endpoint the service user utilizes for validating tokens, because normal end users may not be able to reach that endpoint.

Complete “public” Identity API endpoint. This endpoint should not be an “admin” endpoint, as it should be accessible by all end users. Unauthenticated clients are redirected to this endpoint to authenticate. Although this endpoint should ideally be unversioned, client support in the wild varies. If you’re using a versioned v2 endpoint here, then this should not be the same endpoint the service user utilizes for validating tokens, because normal end users may not be able to reach that endpoint. This option is deprecated in favor of www_authenticate_uri and will be removed in the S release.

Warning

This option is deprecated for removal since Queens. Its value may be silently ignored in the future.

Reason

The auth_uri option is deprecated in favor of www_authenticate_uri and will be removed in the S release.

Reason

Valid Values

None, MAC, ENCRYPT

(Optional) If defined, indicate whether token data should be authenticated or authenticated and encrypted. If MAC, token data is authenticated (with HMAC) in the cache. If ENCRYPT, token data is encrypted and authenticated in the cache. If the value is not one of these options or empty, auth_token will raise an exception on initialization.

Used to control the use and type of token binding. Can be set to: “disabled” to not check token binding. “permissive” (default) to validate binding information if the bind type is of a form known to the server and ignore it if not. “strict” like “permissive” but if the bind type is unknown the token will be rejected. “required” any form of token binding is needed to be allowed. Finally the name of a binding method that must be present in tokens.

hash_algorithms
Type

list

Default

md5

Hash algorithms to use for hashing PKI tokens. This may be a single algorithm or multiple. The algorithms are those supported by Python standard hashlib.new(). The hashes will be tried in the order given, so put the preferred one first for performance. The result of the first hash will be stored in the cache. This will typically be set to multiple values only while migrating from a less secure algorithm to a more secure one. Once all the old tokens are expired this option should be set to a single value for better performance.

Warning

This option is deprecated for removal since Ocata. Its value may be silently ignored in the future.

Reason

PKI token format is no longer supported.

service_token_roles
Type

list

Default

service

A choice of roles that must be present in a service token. Service tokens are allowed to request that an expired token can be used and so this check should tightly control that only actual services should be sending this token. Roles here are applied as an ANY check so any role in this list must be present. For backwards compatibility reasons this currently only affects the allow_expired check.

service_token_roles_required
Type

boolean

Default

false

For backwards compatibility reasons we must let valid service tokens pass that don’t pass the service_token_roles check as valid. Setting this true will become the default in a future release and should be enabled if possible.

This name needs to match one of values mentioned in Keystone deployment’s ‘notification_topics’ configuration e.g. notification_topics=notifications, barbican_notificationsMultiple servers may listen on a topic and messages will be dispatched to one of the servers in a round-robin fashion. That’s why Barbican service should have its own dedicated notification queue so that it receives all of Keystone notifications.
