 | `LRSQL_SSL_PORT`                  | `sslPort`                | The HTTPS port that the webserver will be open on.                                                                                                                                                                                                     | `8443`    |
 | `LRSQL_URL_PREFIX`                | `urlPrefix`              | The prefix of the webserver URL path, e.g. the prefix in `http://0.0.0.0:8080/xapi` is `/xapi`. Used when constructing the `more` value for multi-statement queries. Cannot start with `/admin`. *(Note: Only applies to LRS xapi endpoints, not admin/ui endpoints)*              | `/xapi`   |
 | `LRSQL_PROXY_PATH`                | `proxyPath`              | This path modification is exclusively for use with a proxy, such as apache or nginx or a load balancer, where a path is added to prefix the entire application (such as `https://www.mysystem.com/mylrs/xapi/statements`). This does not actually change the routes of the application, it informs the admin frontend where to look for the server endpoints based on the proxied setup, and thus must be used in conjunction with a third party proxy. If used, the value must start with a leading `/` but not end with one (e.g. `/mylrs` is valid, as is `/mylrs/b` but `/mylrs/` is not). Use with caution. | Not Set |
-| `LRSQL_AUTH_BY_CRED_ID`                | `authByCredId`              | Allows a call to the xAPI endpoints to use the admin account credentials / authorization instead of a call with raw xAPI credentials. Necessary when the xAPI endpoint is behind additional security/SSO and cannot have custom credentials in Authorization header. | false |
