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. |

Finally the name of a binding method that must be present in tokens. |
|
| list value | 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().

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. |

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. |
|
| boolean value | (Optional) Use the advanced (eventlet safe) memcached client pool. The advanced pool will only work under python 2.x. |

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.

| integer value | 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. |
|
| string value | 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. |

|
| string value | Default rule. Enforced when a requested rule is not found. |
|
| multi valued | Directories where policy configuration files are stored. They can be relative to any directory in the search path defined by the config_dir option, or absolute paths. The file defined by policy_file must exist for these directories to be searched. Missing or empty directories are ignored. |
|
| string value | The file that defines policies. |
|
| string value | Content Type to send and receive data for REST based policy check |
|
| string value | Absolute path to ca cert file for REST based policy check |
|
| string value | Absolute path to client cert for REST based policy check |
|
| string value | Absolute path client key file REST based policy check |
|
| boolean value | server identity verification for REST based policy check |
3.1.24. oslo_reports
The following table outlines the options available under the [oslo_reports] group in the /etc/cinder/cinder.conf file.
| Configuration option = Default value | Type | Description |
|---|---|---|
|

|
| string value | Path to a log directory where to create a file |
3.1.25. oslo_versionedobjects

3.1.26. profiler
The following table outlines the options available under the [profiler] group in the /etc/cinder/cinder.conf file.
| Configuration option = Default value | Type | Description |
|---|---|---|
|
| string value | Connection string for a notifier backend. Default value is messaging:// which sets the notifier to oslo_messaging. Examples of possible values:
|
|
| boolean value | Enables the profiling for all services on this node. Default value is False (fully disable the profiling feature). Possible values:
|
|
| string value | Document type for notification indexing in elasticsearch. |
|
| integer value | Elasticsearch splits large requests in batches. This parameter defines maximum size of each batch (for example: es_scroll_size=10000). |
|
| string value | This parameter is a time value parameter (for example: es_scroll_time=2m), indicating for how long the nodes that participate in the search will maintain relevant resources in order to continue and support it. |
|
| string value | Secret key(s) to use for encrypting context data for performance profiling. This string value should have the following format: <key1>[,<key2>,…<keyn>], where each key is some random string. A user who triggers the profiling via the REST API has to set one of these keys in the headers of the REST API call to include profiling results of this node for this particular project. Both "enabled" flag and "hmac_keys" config options should be set to enable profiling. Also, to generate correct profiling information across all services at least one key needs to be consistent between OpenStack projects. This ensures it can be used from client side to generate the trace, containing information from all possible resources. |
|
| string value | Redissentinel uses a service name to identify a master redis service. This parameter defines the name (for example: sentinal_service_name=mymaster). |
|
| floating point value | Redissentinel provides a timeout option on the connections. This parameter defines that timeout (for example: socket_timeout=0.1). |
|
| boolean value | Enables SQL requests profiling in services. Default value is False (SQL requests won’t be traced). Possible values:
|
