[Samba] Problems with Samba as an AD and named

Fri Sep 15 17:08:16 UTC 2023

 Hi Rowland,

I learned a bit from the samba-tools while trying to administer that installation (the most, when I had to move from the former DC to that now and to demote the old one and so on), but I am sure I do not know in deep of that.
With ldapsearch I just know some basics - so basically no.
If it is better I also could make a new reinstall and forget of that zentyal thing. I just was unsure. But the Problem is - because of power and money thoughts the AD DC is on an old laptop and I do not know on which installation I should put it when not there. And if I understood fine, to move from one DC to another the old one has to be online. It is not possible to dump all the information and make a move. Is it? But after all I think it is just a little thing as it ran until yesterday...

Thank you

I wish you had asked before you setup zentyal, because from the sound
of it, you are running a small home domain and you probably do not need
to run bind9, you would have been okay with the internal Samba dns
server.

Your dns records probably are in AD, but before we go down the path of
checking, are you used to running ldapsearch commands and are you aware
of samba-tool ?
