This plugin collection will be released officially in 1.4. It now includes the CIFS connector which allows you to connect to an SMB network share in much the same way that you connect to an HCP namespace. With this connector there is no need to mount the CIFS share and use the LFS connector to crawl it. NOTE: please use this on a test instance. Once installed you will not be able to upgrade to a production version.
