You use Horizon Administrator to configure policies for client sessions.
You can set these policies to affect specific users, specific desktop pools, or all client sessions users. Policies that affect specific users and desktop pools are called user-level policies and desktop pool-level policies. Policies that affect all sessions and users are called global policies.
User-level policies inherit settings from the equivalent desktop pool-level policy settings. Similarly, desktop pool-level policies inherit settings from the equivalent global policy settings. A desktop pool-level policy setting takes precedence over the equivalent global policy setting. A user-level policy setting takes precedence over the equivalent global and desktop pool-level policy settings.
Lower-level policy settings can be more or less restrictive than the equivalent higher-level settings. For example, you can set a global policy to Deny and the equivalent desktop pool-level policy to Allow, or vice versa.
