You can configure domain filters to limit the domains that a Connection Server instance or security server makes available to end users.
Horizon 7 determines which domains are accessible by traversing trust relationships, starting with the domain in which a Connection Server instance or security server resides. For a small, well-connected set of domains, Horizon 7 can quickly determine a full list of domains, but the time that this operation takes increases as the number of domains increases or as the connectivity between the domains decreases. Horizon 7 might also include domains in the search results that you would prefer not to offer to users when they log in to their remote desktops.
If you have previously set the value of the Windows registry key that controls recursive domain enumeration (HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\RecursiveDomainEnum) to false, recursive domain searching is disabled, and the Connection Server instance uses only the primary domain. To use the domain filtering feature, delete the registry key or set its value to true, and restart the system. You must do this for every Connection Server instance on which you have set this key.
The following table shows the types of domain lists that you can specify to configure domain filtering.
|Domain List Type||Description|
|Search exclusion list||Specifies the domains that Horizon 7 can traverse during an automated search. The search ignores domains that are included in the search exclusion list, and does not attempt to locate domains that the excluded domain trusts. You cannot exclude the primary domain from the search.|
|Exclusion list||Specifies the domains that Horizon 7 excludes from the results of a domain search. You cannot exclude the primary domain.|
|Inclusion list||Specifies the domains that Horizon 7 does not exclude from the results of a domain search. All other domains are removed apart from the primary domain.|
The automated domain search retrieves a list of domains, excluding those domains that you specify in the search exclusion list and domains that are trusted by those excluded domains. Horizon 7 selects the first non-empty exclusion or inclusion list in this order.
- Exclusion list configured for the Connection Server instance.
- Exclusion list configured for the Connection Server group.
- Inclusion list configured for the Connection Server instance.
- Inclusion list configured for the Connection Server group
Horizon 7 applies only the first list that it selects to the search results.
If you specify a domain for inclusion, and its domain controller is not currently accessible, Horizon 7 does not include that domain in the list of active domains.
You cannot exclude the primary domain to which a Connection Server instance or security server belongs.
