The chosen port is displayed in the service’s log file.

Finally the name of a binding method that must be present in tokens.

service_token_roles
Type

list

Default

service

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.

service_token_roles_required
