A server receives a consumer request from a client to access a product repository that is coupled to the server. The consumer request comprises an entitlement certificate and a uniform resource locator (URL). The server identifies at least one extended attribute object identifier in the entitlement certificate to determine whether the client is authorized to access the product repository. The at least one extended attribute object identifier has a corresponding URL in the entitlement certificate that specifies a location of the product repository that the client is authorized to access. The server grants the client access to the product repository based on a determination that the URL in the consumer request matches a URL in the entitlement certificate.
