Setting the Certificate Checking Mode in Horizon Client
You can determine whether client connections are rejected if any or some server certicate checks fail by
conguring a seing in Horizon Client.
Certicate checking occurs for SSL connections between the server and Horizon Client. Certicate
verication includes the following checks:
n
Is the certicate intended for a purpose other than verifying the identity of the sender and encrypting
server communications? That is, is it the correct type of certicate?
n
Has the certicate expired, or is it valid only in the future? That is, is the certicate valid according to
the computer clock?
n
Does the common name on the certicate match the host name of the server that sends it? A mismatch
can occur if a load balancer redirects Horizon Client to a server that has a certicate that does not match
the host name entered in Horizon Client. Another reason a mismatch can occur is if you enter an IP
address rather than a host name in the client.
n
Is the certicate signed by an unknown or untrusted certicate authority (CA)? Self-signed certicates
are one type of untrusted CA.
To pass this check, the certicate's chain of trust must be rooted in the device's local certicate store.
To set the certicate checking mode, start Horizon Client and open . In , tap Security
options and tap Security mode. You have three choices:
n
Never connect to untrusted servers. If any of the certicate checks fails, the client cannot connect to the
server. An error message lists the checks that failed.
n
Warn before connecting to untrusted servers. If a certicate check fails because the server uses a self-
signed certicate, you can click Continue to ignore the warning. For self-signed certicates, the
certicate name is not required to match the server name you entered in Horizon Client.
