The ADM and ADMX template files for Horizon Client, vdm_client.adm and vdm_client.admx, contain security-related settings. These settings appear in the Security and Scripting Definitions sections in the Group Policy Management Editor. Unless otherwise noted, these files include only Computer Configuration settings. If a User Configuration setting is available, and you define a value for it, it overrides the equivalent Computer Configuration setting.
For information about these settings and their security implications, see "Security Settings for Client GPOs" in the VMware Horizon Client for Windows Installation and Setup Guide document.
