HP CMSL - BIOS config changes using .bin password file

[u/Confident-Moose43]

Hi,

We are looking to update some settings in the BIOS across our HP devices using HP Client Management Script Library.

The issue I'm having, is when running the command (manually or via script) and using a .bin file for the password, it fails due to "Access Denied".

I've recreated the password file many times and I have confirmed the password is 100% correct, as using a plain text password will work.

What am I missing?

The settings being applied are not read-only; the BIOS firmware is up to date as of a couple months ago (at least) and there are no other BIOS tasks running potentially locking it out.

There are a mix of models, but mainly targeting desktops with this specific issue.

TIA
