[Pkg-samba-maint] Bug#956428: python3-samba: the switch to python3.8 breaks DC functionality on upgrade - samba_dnsupdate fails

[Jeremy Jackson]

Package: python3-samba
Version: 2:4.11.5+dfsg-1+b1
Severity: important

Dear Maintainer,


   * What led up to the situation?
   attempting to update working Samba AD DC on Buster to Testing
   * What exactly did you do (or not do) that was effective (or
   samba tries to update DNS to match changes in it's IP addresses
     ineffective)?
   * What was the outcome of this action?
   samba_dnsupdate is Python, and it fails due to error importing samba.gensec C module
   * What outcome did you expect instead?
   upgrade should have been transparent

   Upstream samba 4.11.6 contains the fix I believe:
git commit f0eb1e623f76d3dbd0c22f96cabebd1041c147df

Avoiding bad call flags with python 3.8, using METH_NOARGS instead of zero.
