Information
If a host is configured to join an Active Directory domain using Host Profiles and/or Auto Deploy, the Active Directory credentials are saved in the profile and are transmitted over the network. To avoid having to save Active Directory credentials in the Host Profile and to avoid transmitting Active Directory credentials over the network, use the vSphere Authentication Proxy.

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.
