[Samba] samba provisioning hangs on "Repacking database from v1 to v2 format"

[Alexander Harm || ApfelQ]

Hello, I installed a fresh Debian Bullseye 11.6 and Samba 4.17.7-Debian from backports. I followed the steps outlined in https://wiki.samba.org/index.php/Setting_up_Samba_as_an_Active_Directory_Domain_Controller
and finally tried to provision the domain with

samba-tool domain provision --use-rfc2307 —interactive

The process starts but then it hangs for hours:

Which I find strange, since it is a clean install out of the box.

Any ideas?
