Dell ThinOS 2211, 2208, and 2205 Release Notes

ThinOS enhancements

1. Admin mode login event on Wyse Management Suite 4.0 server—If you enable admin mode in Wyse Management Suite policy by going to Privacy & Security > Account Privileges and then login, a login event is recorded. This event is recorded in Wyse Management Suite 4.0 server, whether the login is successful or not.
2. Fail to change BIOS settings event on Wyse Management Suite 4.0 server—If you publish the BIOS policy from Wyse Management Suite 4.0 server with a wrong BIOS password, a failure event is recorded. This event is recorded in Wyse Management Suite 4.0 server.
3. Supports new MIB tree in SNMPV3 —ThinOS supports MIB tree 1.3.6.1.4.1.714.1.2.6.1.2.0 to send message to client, and the message character count is increased to 255 characters. ThinOS also supports MIB tree 1.3.6.1.4.1.714.1.2.6.1.1.0 to reboot the client. The reboot client behaviors are as follows:
   • Set to 0: Reboot immediately
   • Set to x: Reboot after x minutes (x is integer)
   • Set to -1: Cancel reboot
     NOTE:If you set 1.3.6.1.4.1.714.1.2.6.1.1.0 to reboot the client, you cannot set another value to change the reboot timer directly. You must set the value to -1 to cancel the reboot first, and then set another value to reboot again.
4. LPD service for printer—A thin client can be configured to provide Line Printer Daemon (LPD ) services, making the thin client a printer server on the network. The LPD printer service is applied with LPT printer and SMB printer.
   NOTE:The LPD service for printer is not supported in AVD/RDP session on ThinOS 2211.
5. Performance Retrospective—You can enable Enable Performance Retrospective option in APT/WMS > Advanced > Services > Troubleshooting Settings. When you click Performance Retrospective in the General tab of the Troubleshooting dialog box, CPU, Memory, and Disk data is displayed.

   

   When you click Networking, Network data like ENET and WLAN is displayed, and the data starts from terminal boot. Five-minute data is displayed by default, and you can select a time span in the list by using Prev and Next buttons.

   

6. VDI with Web Authentication updates
   • Web Authentication Auto Login update: After setting the default credentials in Remote Connections > General Options, when you connect to a VDI Broker agent that uses Web Authentication, the default credentials passes through to the web page automatically.
   • Lock/Unlock Terminal when using Web Authentication method
     • In ThinOS 2208 (9.3.2102), after logging into a VDI Broker agent with Web Authentication and locking the ThinOS session, you must set a temporary password to unlock the system.
     • From ThinOS 2211 (9.3.3099) onwards, a temporary password is not required. You can use the password that is used at the time of logging in to unlock the system directly.
   • Tested scenarios: In case any other (or custom) web authentication pages are used, correct caching of the credentials, which results in behavior similar to ThinOS 2208 or earlier versions, cannot be guaranteed . The tested scenarios are as follows:
     • Citrix Federated Authentication Service SAML with Microsoft Azure Active Directory
     • Citrix ADC Native OTP
     • Citrix ADC MFA with SAML using OKTA as IDP and Citrix FAS for SSO to VDA
     • Horizon Workspace One Mode (On-premises)
     • Horizon Workspace One Mode (WS1 Access)
     • Horizon Workspace One Mode (WS1 Access) with OKTA IDP
     • VMware Unified Access Gateway with OKTA IDP
     • VMware Unified Access Gateway with Microsoft Azure IDP
     • Azure Virtual desktop Broker agent
7. Updated the First Boot Wizard import configuration password character limit from eight to nine—When importing the system settings configuration in First Boot Wizard, the minimum password character limit is nine characters.
8. VPN Update—GlobalProtect with .pfx certificate feature is added.
9. Secure MQTT connection for the Wyse Management Suite cloud server—When the client checks in to the Wyse Management Suite cloud server, the MQTT connection is routed to a secure MQTT connection. If the secure MQTT connection fails, the cloud server falls back to a nonsecure MQTT connection.

10. SCEP renewal interval update—If the client fails to renew the certificate, the SCEP renewal interval changes from 20 s to 12 hours.

11. Enabled SD card support on OptiPlex 5400 All-in-One—The SD card slot on OptiPlex 5400 All-in-One is not a USB port. You cannot redirect SD card to VDI sessions. You can only map the SD card to Citrix and RDP sessions as a disk.

12. SMB printer update— If the SMB printer credentials field is left empty, the client uses the login credentials (not the web login authentication credentials) as the SMB printer credentials.
    NOTE: In the local printer setup window, if you want to do a local SMB printer test, you must first add and save the SMB credentials manually, and then do a test print.
13. After logging in using Citrix, VMware, or Microsoft webview Broker agent on the client, the last username that was used to log in is recorded in the Wyse Management Suite server device list page and device details page.
