Change BIOS password with Wyse management suite

Hi,

There is an issue with the feature that changes bios password with the wyse management suite.

Once the password is set in Jobs > More actions -> Sync BIOS Admin Password, using this documentation https://www.dell.com/support/manuals/fr-fr/wyse-wms/wyse-wms_3.0_ag/sync-bios-admin-password?guid=guid-92bbb2b9-96c0-4cb4-bca2-37866e2c0cf8&lang=en-us

This doesn't work on the client. They show the error "BIOS : settings change failed"

The clients run ThinOS 9.

Why, in the "Sync BIOS Admin Password" menu, it doesn't ask for the current password first, then the new password, but only the new password to be set ? Is it because of that ?

Is there another way to do this, like running a script, or using cctk ?

Thanks
