n
Does the common name on the certificate 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 certificate 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 certificate signed by an unknown or untrusted certificate authority (CA)? Self-signed certificates
are one type of untrusted CA.
To pass this check, the certificate's chain of trust must be rooted in the device's local certificate store.
NOTE For instructions about distributing a self-signed root certificate and installing it on Mac OS X client
systems, see the Advanced Server Administration document for the Mac OS X Server you are using, available
from the Apple Web site.
In addition to presenting a server certificate, View Connection Server also sends a certificate thumbprint to
Horizon Client. The thumbprint is a hash of the certificate public key and is used as an abbreviation of the
public key. If the View server does not send a thumbprint, you see a warning that the connection is
untrusted.
If your administrator has allowed it, you can set the certificate checking mode. Select VMware Horizon
View Client > Preferences (Horizon Client 3.0) or VMware Horizon Client > Preferences (Horizon Client
3.1 and later) from the menu bar. You have three choices:
n
Never connect to untrusted servers. If any of the certificate 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 certificate check fails because the server uses a self-
signed certificate, you can click Continue to ignore the warning. For self-signed certificates, the
certificate name is not required to match the View Connection Server name you entered in
Horizon Client.
n
Do not verify server identity certificates. This setting means that View does not perform any certificate
checking.
If the certificate checking mode is set to Warn, you can still connect to a View Connection Server instance
that uses a self-signed certificate.
If an administrator later installs a security certificate from a trusted certificate authority, so that all certificate
checks pass when you connect, this trusted connection is remembered for that specific server. In the future,
if that server ever presents a self-signed certificate again, the connection fails. After a particular server
presents a fully verifiable certificate, it must always do so.
Searching for Desktops or Applications
After you connect to a View server, the available desktops and applications on that server appear on the
desktop and application selection window. You can search for a particular desktop or application by typing
in the window.
When you begin to type, Horizon Client highlights the first matching desktop or application name. To
connect to a highlighted desktop or application, press the Enter key. If you continue to type after the first
match is found, Horizon Client continues to search for matching desktops and applications. If
Horizon Client finds multiple matching desktops or applications, you can press the Tab key to switch to the
next match. If you stop typing for two seconds and then begin to type again, Horizon Client assumes that
you are starting a new search.
