The Centrify Client for Linux does not require a connector. However, at least one connector is required to manage the Linux systems and accounts using the Privileged Access Service. The connector also provides a built-in web server proxy to forward HTTPS connection requests to the Privileged Access Service.
The CLI toolkit required Linux computers to be joined to an Active Directory domain and have the adclient process running locally. The Centrify Client for Linux that replaces the CLI toolkit does not require the Linux computer to be joined to a domain or have the adclient process installed.
