auth_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.

auth_version¶

Type:	string
Default:	<None>

API version of the admin Identity API endpoint.

delay_auth_decision¶

Type:	boolean

Default:	300

In order to prevent excessive effort spent validating tokens, the middleware caches previously-seen tokens for a configurable duration (in seconds). Set to -1 to disable caching completely.

revocation_cache_time¶

Type:	integer
Default:	10

Determines the frequency at which the list of revoked tokens is retrieved from the Identity service (in seconds). A high number of revocation events combined with a low cache duration may significantly reduce performance. Only valid for PKI tokens. This option has been deprecated in the Ocata release and will be removed in the P release.

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.

memcache_security_strategy¶

(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.

memcache_secret_key¶

Type:	string

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.

check_revocations_for_cached¶

Type:	boolean
Default:	false

If true, the revocation list will be checked for cached tokens. This requires that PKI tokens are configured on the identity server.

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.

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.
