Horizon Agent Configuration Settings
You can use GPO template on the agent OS to turn off True SSO at the pool level or to change
defaults for certificate settings such as key size and count and settings for reconnect attempts.
Note The following table shows the settings to use for configuring the agent on individual virtual
machines, but you can alternatively use the Horizon Agent Configuration template files. The ADMX
template file is named (vdm_agent.admx). Use the template files to make these policy settings
apply to all the virtual machines in a desktop or application pool. If a policy is set the policy takes
precedence over the registry settings.
The ADMX files are available in VMware-Horizon-Extras-Bundle-x.x.x-yyyyyyy.zip, which
you can download from the VMware Downloads site at
https://my.vmware.com/web/vmware/
downloads. Under Desktop & End-User Computing, select the VMware Horizon 7 download,
which includes the ZIP file.
