The Directory Importer is a component of the Netskope Adapters that connects to the domain controller and periodically fetches user and group information to post that info to your tenant instance in the Netskope cloud1. If you are having issues with this process, the first thing you should investigate is the Directory Importer itself. You can check the status of the Directory Importer service, the configuration file, the logs, and the connectivity to the domain controller and the Netskope cloud2. Therefore, option B is correct and the other options are incorrect. References: Configure Directory Importer - Netskope Knowledge Portal, Troubleshooting Directory Importer - Netskope Knowledge Portal
