When you join a host to a directory service domain, you can use the vSphere Authentication Proxy server for authentication instead of transmitting user-supplied Active Directory credentials.
Before you begin
Verify that the vSphere Client is connected to the host.
If ESXi is configured with a DHCP address, set up the DHCP range as described in the vSphere Security documentation..
If ESXi is configured with a static IP address, verify that its associated profile is configured to use the vSphere Authentication Proxy service to join a domain so that the authentication proxy server can trust the ESXi IP address.
If ESXi is using a self-signed certificate, verify that the host has been added to vCenter Server. This allows the authentication proxy server to trust ESXi.
If ESXi is using a CA-signed certificate and is not provisioned by Auto Deploy, verify that the CA certificate has been added to the local trust certificate store of the authentication proxy server as described in the vSphere Security documentation.
Authenticate the vSphere Authentication Proxy server to the host as described in the vSphere Security documentation.
