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.

(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.

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.

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.

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.
