This has no effect unless global and token caching are enabled.</td> </tr> <tr> <td>caching = True</td> <td>(BoolOpt) Toggle for token system cacheing. This has no effect unless global caching is enabled.</td> </tr> <tr> <td>driver = keystone.token.persistence.backends.sql.Token</td> <td>(StrOpt) Token persistence backend driver.</td> </tr> <tr> <td>enforce_token_bind = permissive</td> <td>(StrOpt) Enforcement policy on tokens presented to Keystone with bind information. One of disabled, permissive, strict, required or a specifically required bind mode, e.g., kerberos or x509 to require binding to that authentication.</td> </tr> <tr> <td>expiration = 3600</td> <td>(IntOpt) Amount of time a token should remain valid (in seconds).</td> </tr> <tr> <td>hash_algorithm = md5</td> <td>(StrOpt) The hash algorithm to use for PKI tokens. This can be set to any algorithm that hashlib supports. WARNING: Before changing this value, the auth_token middleware must be configured with the hash_algorithms, otherwise token revocation will not be processed correctly.</td> </tr> <tr> <td>provider = None</td> <td>(StrOpt) Controls the token construction, validation, and revocation operations. Core providers are "keystone.token.providers.[pkiz|pki|uuid].Provider". The default provider is pkiz.</td> </tr> <tr> <td>revocation_cache_time = 3600</td> <td>(IntOpt) Time to cache the revocation list and the revocation events if revoke extension is enabled (in seconds). This has no effect unless global and token caching are enabled.</td> </tr> <tr> <td>revoke_by_id = True</td> <td>(BoolOpt) Revoke token by token identifier. Setting revoke_by_id to true enables various forms of enumerating tokens, e.g. `list tokens for user`. These enumerations are processed to determine the list of tokens to revoke. Only disable if you are switching to using the Revoke extension with a backend other than KVS, which stores events in memory.</td> </tr> </tbody> </table> </para>
