| boolean value | Show SQLAlchemy pool-related debugging output in logs (sets DEBUG log level output) if specified. |
| integer value | 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. |
| integer value | Size of pool used by SQLAlchemy. This is the largest number of connections that will be kept persistently in the pool. Can be set to 0 to indicate no size limit.

| boolean value | Use JSON formatting for logging. This option is ignored if log_config_append is set. |
| boolean value | Use syslog for logging. Existing syslog format is DEPRECATED and will be changed later to honor RFC5424. This option is ignored if log_config_append is set. |
| boolean value | Log output to Windows Event Log. |
| boolean value | Log output to standard error. This option is ignored if log_config_append is set. |
| boolean value | Uses logging handler designed to watch file system. When log file is moved or removed this handler will open a new log file with specified path instantaneously. It makes sense only if log_file option is specified and Linux platform is used. This option is ignored if log_config_append is set. |
| integer value | Size of the pool of greenthreads used by wsgi |
| boolean value | If False, closes the client socket connection explicitly. |

| string value | Authentication type to load |
| 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. This option is deprecated in favor of www_authenticate_uri and will be removed in the S release. Deprecated since: Queens *Reason:*The auth_uri option is deprecated in favor of www_authenticate_uri and will be removed in the S release. |

| string value | The region in which the identity server can be found. |
| list value | 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. |
| boolean value | 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. |
| string value | The name or type of the service as it appears in the service catalog. This is used to validate tokens that have restricted access rules. |
| 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. |

| integer value | Define the number of max threads to be used for notification server processing functionality. |
| string value | Keystone notification queue topic name. 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. Alternatively if the chosen oslo.messaging backend supports listener pooling (for example rabbitmq), setting a non-default pool_name option should be preferred. |
