Fix Recommendation

From the vSphere Client, go to Home >> Host Profiles and select a Host Profile to edit.

View the settings under Security and Services >> Security Settings >> Authentication Configuration >> Active Directory Configuration >> Join Domain Method.

Set the method used to join hosts to a domain to "Use vSphere Authentication Proxy to add the host to domain" and provide the IP address of the vSphere Authentication Proxy server.

Check Contents

From the vSphere Client, go to Home >> Host Profiles and select a Host Profile to edit.

View the settings under Security and Services >> Security Settings >> Authentication Configuration >> Active Directory Configuration >> Join Domain Method.

Verify the method used to join hosts to a domain is set to "Use vSphere Authentication Proxy to add the host to domain".

or

From a PowerCLI command prompt while connected to vCenter, run the following command:

Get-VMHost | Select Name, ` @{N="HostProfile";E={$_ | Get-VMHostProfile}}, ` @{N="JoinADEnabled";E={($_ | Get-VmHostProfile).ExtensionData.Config.ApplyProfile.Authentication.ActiveDirectory.Enabled}}, ` @{N="JoinDomainMethod";E={(($_ | Get-VMHostProfile).ExtensionData.Config.ApplyProfile.Authentication.ActiveDirectory | Select -ExpandProperty Policy | Where {$_.Id -eq "JoinDomainMethodPolicy"}).Policyoption.Id}}

Verify that if "JoinADEnabled" is "True", "JoinDomainMethod" is "FixedCAMConfigOption".

If not using Host Profiles to join active directory, this is not a finding.
