[Samba] domain member file server failed after upgrade from 4.11.14 to 4.13.2

[MORILLO Jordi]

Hi Rowland,
Sorry to inform that none of thus packages solve my problem.

But today, with some Tranquil.it helps, I have some news:

- Upgrade from 4.11.14 -> 4.12.9 is OK
- Upgrade from 4.12.9 -> 4.13.2 : problem is present with Tranquil.it AND Louis package
- Fresh install + member join with 4.13.2 is OK (Centos AND Buster packages)

Problem only occur when upgrading member to 4.13.2 with Windows 2016 DC.
Here is some interesting parts of net ads testjoin -d99 between 4.11.14 and 4.13.2:

4.11.14 (working)
