Because ESXi does not support vCenter Single Sign-On, it does not support the identity sources you set up with vCenter Single Sign-On. You can add an ESXi host to an Active Directory Domain from the vSphere Web Client.


  1. In the vSphere Web Client, select the ESXi host.
  2. In the Settings tab, select Authentication Services in the System area.
  3. Click Join Domain, supply the domain settings, and click OK.
