Hello Andreas and thanks for this bug report. I can reproduce the issue you describe on Focal and Hirsute. A very similar command is given as an example in pmt-ehd's manpage (pmt-ehd(8), not installed by libpam-mount- bin but available in the source package, see [1]).
I'm marking this bug as Triaged and subscribing the Ubuntu Server Team to it.
