Re: [Samba] using samba with bind dlz




I found the
file /usr/lib64/python2.7/site-packages/samba/provision/sambadns.py
I was looking through it and seemed to come across the area where I am
having problems.

In the create_dns_dir function

I wanted to see what paths.dns had and what dns_dir where getting set to.

so I did a simple print and found

paths.dir is set
to /var/lib/samba/private/dns/fedora.methanemaker.mooo.com.zone
and
dns_dir is set to /var/lib/samba/private/dns

next I check those directories

[root@dc1 ~]# ls -l
/var/lib/samba/private/dns/fedora.methanemaker.mooo.com.zone
ls: cannot access
'/var/lib/samba/private/dns/fedora.methanemaker.mooo.com.zone': No such
file or directory
[root@dc1 ~]# mkdir -p
/var/lib/samba/private/dns/fedora.methanemaker.mooo.com.zone

it looks like samba-tool removes that directory

I'll keep looking for the culprit in that function.
