[docs]def symptom_unreasonable_max_token_size(): """`keystone.conf [DEFAULT] max_token_size` should be adjusted. This option is intended to protect keystone from unreasonably sized tokens, where "reasonable" is mostly dependent on the `keystone.conf [token] provider` that you're using. If you're using one of the following token providers, then you should set `keystone.conf [DEFAULT] max_token_size` accordingly: - For Fernet, set `keystone.conf [DEFAULT] max_token_size = 255`, because Fernet tokens should never exceed this length in most deployments. However, if you are also using `keystone.conf [identity] driver = ldap`, Fernet tokens may not be built using an efficient packing method, depending on the IDs returned from LDAP, resulting in longer Fernet tokens (adjust your `max_token_size` accordingly). """ return ('fernet' in CONF.token.provider and CONF.max_token_size > 255)
