VMware Horizon View Client for Linux Help : Certificate Checking Modes for View Client

Certificate Checking Modes for View Client
Administrators and sometimes end users can configure whether client connections are rejected if any or some server certificate checks fail.
Certificate checking occurs for SSL connections between View Connection Server and View Client. Certificate verification includes the following checks:
To pass this check, the certificate's chain of trust must be rooted in the device's local certificate store.
In addition to presenting a server certificate, View Connection Server 4.6.1, 5.0.1, and later versions also send a certificate thumbprint to View 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 File > Preferences from the VMware Horizon View Client menu bar or the View desktop menu bar. You have three choices:
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.
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 View Client.
Do not verify server identity certificates. This setting means that View does not perform any certificate checking.
