It’s in the archives with the subject "winbind use default domain problem after upgrade”. I was using Louis’ packages and winbind running on the same domain member machine. Back then I was upgrading from 4.10.5 to 4.13.2 but to me it looked like Ubuntu version was the reason more than anything changing in Samba specifically.

AFAIR I tested many versions between 4.10 and 4.13 to find where it broke, but I could only reproduce it with an upgrade to Ubuntu 20, not with any specific Samba update.
