Hello, thanks for your response.

It's a DC server (both, debian 8 and debian 9 servers are DC's together).

The configure command line I've used is:
./configure --enable-gnutls --with-gpgme --with-static-modules=ALL
--with-systemd --prefix='/server/samba/bin/'
--sysconfdir='/server/samba/conf/'

and my systemd file is:
[Unit]
Description=Samba Active Directory Domain Controller
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
ExecStart=/server/samba/bin/sbin/samba -D
PIDFile=/server/samba/bin/var/run/samba.pid

[Install]
WantedBy=multi-user.target


I've built both with same configuration and I use the same Systemd file. Of
course I've compiled every samba on their machine and is not a copy from
one to other.

Thanks!!
