Table 3‑5. Horizon Client Configuration Template: Security Settings (Continued)
Setting Description
Ignore incorrect usage
problems
(Computer Configuration setting)
(View 4.6 and earlier releases only) Determines whether errors that are
associated with incorrect usage of a server certificate are ignored. These errors
occur when the server sends a certificate that is intended for a purpose other
than verifying the identity of the sender and encrypting server communications.
Ignore unknown certificate
authority problems
(Computer Configuration setting)
(View 4.6 and earlier releases only) Determines whether errors that are
associated with an unknown Certificate Authority (CA) on the server certificate
are ignored. These errors occur when the server sends a certificate that is signed
by an untrusted third-party CA.

Configuration ADM template file. All RDP settings are User Configuration settings.
