#   value
#   Defaults to $::os_service_default.
#
# [*enforce_token_bind*]
#   (Optional) 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

#
# [*memcache_pool_maxsize*]
#   (Optional) Maximum total number of open connections to every memcached
#   server. Integer value
#   Defaults to $::os_service_default.
#
# [*memcache_pool_socket_timeout*]
#   (Optional) Number of seconds a connection to memcached is held unused in

# [*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.
#   Defaults to $::os_service_default.
#
# [*memcache_use_advanced_pool*]
#   (Optional)  Use the advanced (eventlet safe) memcached client pool. The
#   advanced pool will only work under python 2.x Boolean value
#   Defaults to $::os_service_default.
#
# [*memcached_servers*]
#   (Optional) Optionally specify a list of memcached server(s) to use for
#   caching. If left undefined, tokens will instead be cached in-process.
#   Defaults to $::os_service_default.
#
# [*manage_memcache_package*]
#  (Optional) Whether to install the python-memcache package.
#  Defaults to false.
#

#   Defaults to $::os_service_default.
#
# [*token_cache_time*]
#   (Optional) 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. Integer value
#   Defaults to $::os_service_default.
#
# [*service_token_roles_required*]
#   (optional) backwards compatibility to ensure that the service tokens are
#   compared against a list of possible roles for validity
#   true/false
#   Defaults to $::os_service_default.
#
# DEPRECATED PARAMETERS
#
# [*check_revocations_for_cached*]
#   (Optional) If true, the revocation list will be checked for cached tokens.
#   This requires that PKI tokens are configured on the identity server.
#   boolean value.
#   Defaults to undef.
#
# [*hash_algorithms*]
#   (Optional) 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. List value.
#   Defaults to undef.
