Dell ThinOS 9.1.4097, 9.1.4234, 9.1.5067, and 9.1.6108 Administrator’s Guide

What is new in ThinOS 9.1.5067?

• Citrix Workspace app updates
  • Citrix Workspace App logs can only be exported from ThinOS Troubleshooting > General > Export Logs. See, Export Citrix Workspace app logs.
  • From Citrix Workspace App 2109 and ThinOS 9.1.5067 onwards, only the Server Default mode uses the Scancode. Other Keyboard layout modes such as Specific Keyboard, Client Setting and Dynamic Sync use the default Unicode. There are no changes to the other keyboard layout modes in Citrix Workspace App 2109. For information about how to configure the setting, see Keyboard layout server default mode enhancement.
  • In Citrix VDA 2109 and later versions, the Citrix VDA policy setting Virtual channel allow list is enabled by default. As a result, the non-Citrix virtual channels, such as Zoom, WebEx VDI, WebEx Meetings VDI, JVDI, Imprivata OneSign and HID do not work. You must disable the setting, or find the name of the third-party virtual channel and add it to the virtual channel allow list. For more information, see the Citrix documentation at docs.citrix.com.
• Azure Virtual Desktop (AVD) updates
  • Windows Virtual Desktop (WVD) is renamed to Azure Virtual Desktop (AVD).
  • Supports camera redirection in an RDP session. See, Use camera redirection in an RDP session.
• VMware Horizon Blast updates—Review the limitations for the VMware Horizon Blast. See the Dell Wyse ThinOS 9.1.4234 and 9.1.5067 release notes at www.dell.com/support.
• Wyse Management Suite policy settings and Admin Policy Tool updates
  • Added the Manual override option for selected settings. When enabled, the configured policies from Wyse Management Suite are not applied to the ThinOS device. See, Manual override.
  • Added the Camera option in Peripheral Management. When you disable this option and connect the camera to the device, the device list in the Peripherals window shows empty data. The display resolution list on the device only shows resolutions from the DDC table.
  • Changed the Mute option in Peripheral Management > Audio to a drop-down list. Use this option to control the playback audio and system beep separately.
  • Added the Resolutions From DDC Table Only option under Peripheral Management > Monitor. When enabled, the display resolution list on the device only shows resolutions from the DDC table.
  • Added the Ignore Server Certificate Check option under Privacy & Security > SCEP.

    This option is disabled by default. You must install a CA certificate first and then request a SCEP certificate by using the administrator URL. When using the administrator URL, you must FQDN with prefix HTTPS. Do not use the IP address in the URL.

    If this option is enabled, there is no need to install the CA certificate on the client. You can directly request for a SCEP certificate by using the administrator URL with prefix HTTPS.

    NOTE:If you are using earlier versions of ThinOS and if you have used the IP address in the administrator URL with the Ignore Server Certificate Check option disabled, you must change the URL to FQDN. If the Ignore Server Certificate Check option is enabled, there is no need to change the IP address in the administrator URL.
  • The application name WVD is changed to AVD in the Proxy Application List field under Network Configuration > Proxy Settings.
  • Added the Show Applications with KEYWORDS:Mandatory option under Session Settings > Citrix Session Settings. When this option is enabled and you log in with classic mode or modern mode, only the applications that are configured with KEYWORDS:Mandatory are displayed on the ThinOS desktop.
  • Added the Login Expire Time option under Broker Settings > Citrix Virtual Apps and Desktops Settings. Use this option to set a timer after you log in to a Citrix session. After the countdown timer expires, you must enter the user credentials again to launch any new desktop or application. After you enter the credentials, the countdown timer starts again. Desktop or applications that you launch before the expiry of the countdown timer remains open and are not affected by this setting.
  • The On Desktop=None option under Session Settings > Global Session Settings is not applicable to Modern desktop.
  • Values of Keyboard Layout and Screen Saver Timeout from the client are displayed under System Information on the Devices Details page on Wyse Management Suite.
• VDI enhancements—Ability to dynamically configure the VDI settings—Citrix, VMware, and Zoom plug-in—using Wyse Management Suite or Admin Policy Tool. See, Configuring the VDI dynamic settings.
• ThinOS local enhancements
  • Supports device registration to Wyse Management Suite using secure DNS records. See, Register devices using secure DNS records.
    NOTE:Registering devices to Wyse Management Suite using secure DHCP option tag is not supported in this release.
  • Supports NTFS USB drive mapping.
  • Supports multiple DNS domain suffixes.
  • Ability to save a new password specified in the prompt window when the current WPA and WPA2 personal wireless connection password is incorrect.
  • Supports authentication to domain controller (NTLM) using the None broker. See, Authenticate the domain controller (NTLM) with None broker.
  • Displays a message on the First Boot Wizard screen when you reset the device to factory default settings without a network connection.
  • The application name WVD is changed to AVD for the Apply proxy server on field.
