we are not using Oauth for login.

By default this component is active, so why it is giving an error in some environments and not others. Any idea?

Can someone help please?

I do not even know what triggered this. This is running as a scheduler on its own. Could this be due to any permissions issue on a built-in system user?

Does anyone know what is the reason for this error.15.11.2018 03:07:23.000 *ERROR* [sling-default-199-Registered Service.1444] com.adobe.granite.oauth.server.impl.AccessTokenCleanupTask AccessTokenCleanupTask: General failure while trying to cleanup tokensjavax.jcr.LoginException: Cannot derive user...
