The fact is bind9 is right. There is no to
/var/lib/samba/private/dns/sam.ldb.
There is a sam.ldb: to /var/lib/samba/private/dns/sam.ldb.
A directory "dns" wa not created under  
/var/lib/samba/private/dns/sam.ldb
But, there in:  /var/lib/lib/samba/bind-dns/

ls -la /var/lib/lib/samba/bind-dns/ 
insgesamt 24
drw------- 3 root bind 4096 Mai 20 13:09 .
drwxr-xr-x 4 root root 4096 Mai 21 09:26 ..
drwxrwxr-x 3 root bind 4096 Mai 20 13:02 dns    < -------------------- right
olace
-rw-r----- 2 root bind  427 Mai 20 13:02 dns.keytab
-rwxrwx--- 1 root bind  986 Mai 20 13:09 named.conf
-rw-r--r-- 1 root root 2059 Mai 20 13:02 named.txt

And there is sam.ldb
ls -la /var/lib/lib/samba/bind-dns/dns
insgesamt 3552
drwxrwxr-x 3 root bind    4096 Mai 20 13:02 .
drw------- 3 root bind    4096 Mai 20 13:09 ..
-rw-rw---- 1 root bind 3620864 Mai 20 13:02 sam.ldb
drwxrwx--- 2 root bind    4096 Mai 20 13:02 sam.ldb.d

How can I fix this . A softlik does not work.

Greetings
Daniel

2nd DC ?

If so, use samba_upgradedns to 'upgrade to the internal dns server, then  
immediately use the same tool to upgrade to bind9 again. This should fix  
your problem.
