Hi,
sorry for crossposting (see below), but as it has probably something to
do with Gnuk implementation I want to try here. Maybe someone has an idea.
Kind regards

Hello everyone,
we realized (because of the question of a user), that there are
conditions in which GnuPG is not questioning to short PIN for admin.
This seems to be specific for Gnuk devices, as I could not reproduce on
OpenPGP Card 2.1
This is what happened:
* factory-reset of device (NK Start with Gnuk 1.2.6, maybe other
versions are affected as well)
* 'gpg --card-edit' -> admin -> passwd -> 3 -> '12345678' to 'newpin'
* "PIN changed." message stated that everything is fine, although admin
needs 8 character
* neither '12345678' nor 'newpin' is accepted afterwards
This is on GnuPG 2.2.3 on Arch Linux (which should not matter).
What shall I do, file a bug? Is this a bug in GnuPG or Gnuk? This seems
to be related to the admin-less mode, although changing admin PIN first
shouldn't trigger this, does it?
Kind regards
Alex
