-=== Save Settings in the Database
-
-If you run a clustered setup, the following method configuring the OpenID Connect app is preferred, because it is stateless. The app checks for settings in the database first. If none are found, it falls back to the settings stored in `config.php`. The settings are stored as a JSON formatted string with the following keys and values: 
-
-[width="50%",cols="40%,50%",options="header"]
-|===
-| Key
-| Value
-
-| appid
-| 'openidconnect'
-
-| configkey
-| 'openid-connect'
-
-| configvalue
-| _JSON-String_
-|===
-
-If a malformed JSON string is found, an error is logged. The _key->value_ pairs are the same as when storing them to the `config.php` file. This task has to be done by invoking an occ command, see the following example. Use the occ commands `config:app:get` to view the current setting or `config:app:delete` to delete it. See the xref:configuration/server/occ_command.adoc#config-commands[Config Command Set] for more details.
