Horizon Cloud supports the use of Active Directory Domain Controllers that have the Domain controller: LDAP server signing requirements security policy setting set to Require signing.

Horizon Cloud uses secure Generic Security Services Application Program Interface (GSSAPI) LDAP binds, with both signing and sealing enabled. This feature provides both LDAP data integrity and privacy. This feature also gives Horizon Cloud pods the ability to connect to Domain Controllers that have the Domain controller: LDAP server signing requirements security policy setting set to Require signing.
