Enable ThinOS to check the server certificate common name

ThinOS-based clients check the common name of the server certificate when setting up an SSL connection in full security mode. Use Wyse Management Suite or Admin Policy Tool on ThinOS to enable or disable the TLS checker.

1. Open the Admin Policy Tool on ThinOS or go to the ThinOS 9.x policy settings on Wyse Management Suite.
2. In the Advanced tab, expand Privacy & Security, and click Security Policy.
3. Click the TLS Check CN toggle switch to enable the option.
   Enabling the option allows ThinOS client to check the common name of the server certificate when setting up an SSL connection in full security mode. This option is ineffective to SSL connections for VMware View, Amazon WorkSpaces, and VPN. The server certificate common name is verified all the time when setting up SSL connections for VMware View, Amazon WorkSpaces, and VPN.

   NOTE:Use NetBIOS or FQDN values to define an SSL (HTTPS) connection when enabling the TLSCheckCN option. Enabling the TLSCheckCN option results in SSL connection failure when an IP address is defined.
4. Click Save & Publish.
