[Samba] using samba with bind dlz




I am trying to setup samba as a dc using bind dlz

I'm not sure how much I need to setup on bind before I can use it. I did
the following check.

[root@dc1 ~]# named -V | sed 's/ /\n/g'| grep '\-\-' |grep -e gssapi -e
dlopen
'--with-dlopen=yes'
'--with-gssapi=yes'

I am using the default config for samba that came with Fedora Rawhide.
I wanted to try out the newly built samba-4.7rc1 that was recently built
with ad support for it.

I'm willing to try out a few things. I'll do the internal dns if I can't
get bind working but I wanted to try bind with dlz ike I have working in
ubuntu.

Here is what happens

[root@dc1 ~]# named -V | sed 's/ /\n/g'| grep '\-\-' |grep -e gssapi -e
dlopen
'--with-dlopen=yes'
'--with-gssapi=yes'
[root@dc1 ~]# samba-tool domain provision --use-rfc2307 --interactive
