Service user configuration

The URL handler requires a service user mapping for detecting client libraries located at /apps or /libs with “allowProxy” mode, to rewrite resource URLs pointing to them to /etc.clientlibs.

Create a principal-based service user mapping with an entry like this:

  org.apache.sling.serviceusermapping.impl.ServiceUserMapperImpl.amended-myapp-wcmio-handler-url
    user.mapping=["io.wcm.handler.url:clientlibs-service\=[sling-scripting]"]

The built-in principal sling-scripting has read access to /apps and /libs.

This configuration is required on both author and publish instances.
