[Samba] Some strange errors in logs

Hai, 

cat "/var/lib/samba/private/named.conf"  also please. 
And check if the correct bind9_dlz is enabled. 

dpkg -l | grep bind9
Jessie, should be 9.9 
Stretch should be 9.10
If this server was upgraded then you need to manualy adjust the file above. 
Looks to my bind9-dlz is enable in smb.conf but not loaded. 

cat /var/log/daemon.log | grep dlz
You should see thing like: 
samba_dlz: starting configure 
samba_dlz: configured writeable zone '... 
And make sure you see _msdcs.your.domain.tld 



Greetz, 

Louis

Hi Louis
Yes the system was upgraded from Jessie to Stretch on DC1 but DC2 was built
from scratch on Debian Stretch 9.2

/var/lib/samba/private/named.conf
dlz "AD DNS Zone" {
    # For BIND 9.8.x
    # database "dlopen
/usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9.so";
    # For BIND 9.9.x
    # database "dlopen
/usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9_9.so";
    # For BIND 9.10.x
     database "dlopen
/usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9_10.so";
    # For BIND 9.11.x
    # database "dlopen
/usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9_11.so";
};
dpkg -l | grep bind9 gives:

ii  bind9                             1:9.10.3.dfsg.P4-12.3+deb9u3   amd64

cat /var/log/daemon.log | grep dlz
don't give:
samba_dlz: starting configure 
samba_dlz: configured writeable zone 
but there are a lot of records about started, update, committed or denied
transactions. 

named -V
BIND 9.10.3-P4-Debian

Shouldn't libbind9-90 be libbind9-140 (1:9.10.3.dfsg.P4-12.3+deb9u3) ?

[Samba] Some strange errors in logs

+1 "penny" :-) :-) for my thoughts..  :-p  

But yes, that should fix it. 
I also suggest, review your logs, you wil notice more messages. 
Rsyslog/apt/snmp/postfix/ntp need manual changes after the upgrade. 
At least these, maybe more but these are the one i've encountered.
