For systems that have no local user accounts, other than "root" and/or "vpxuser", this is not applicable. For environments that do not use vCenter server to manage ESXi, this is not applicable. From the vSphere Web Client select the ESXi host and go to Manage >> Authentication Services and view the "Enable Smart Card Authentication" status. If "Enable Smart Card Authentication" is checked, the system requires smart cards to authentication to an Active Directory Domain. For systems that do not use smart cards with Active Directory and do have local user accounts, other than "root" and/or "vpxuser", this is a finding.

Fix Text (F-100627r1_fix)
The following are pre-requisites to configuration smart card authentication for the ESXi DCUI: -Active Directory domain that supports smart card authentication, smart card readers, and smart cards. -ESXi joined to an Active Directory domain. -Trusted certificates for root and intermediary certificate authorities. From the vSphere Web Client select the ESXi Host and go to Manage >> Authentication Services and edit the Smart Card Authentication configuration to add trusted certificate authority certificates and select "Enable Smart Card Authentication" and click "OK". For more information see the vSphere 6.5 documentation on VMware's website.
