I currently manage a small network with mostly Win Server 2016 hosts in a standard Active Directory domain, plus a couple RHEL 7 boxes. We will be going to Win Server 2019 and RHEL 8 in the medium future. Switches and routers are Cisco.

Someone up the chain of command really wants the RHEL and Cisco boxes to be authenticating via Kerberos. My initial internet survey is pulling up various third-party solutions which suggests that this doesn't come easily in built-in MS Kerberos. I'm seeing some tools: e.g. ktpass generates the keytab file on Windows, realm manages client on RHEL. Cisco documentation is not super helpful. Anybody doing this?

    Redhat has some documentation on the process. Uses tooling available from standard repos: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/integrating_rhel_systems_directly_with_windows_active_directory/connecting-rhel-systems-directly-to-ad-using-sssd_integrating-rhel-systems-directly-with-active-directory – JG7 Nov 02 '21 at 23:27
