Description Tim Herrmann (mail address dead) 2018-06-27 13:02:46 UTC
We're having an Active-Directory forest with 4 Windows Server 2008 R2 Domain Controller and 1 Windows Server 2016 DC and the hole forest is running with an Active Directroy 2008 schema.

To get away from the terrible Windows servers we are trying to migrate the Active Directory to SAMBA4 DCs.

I've installed one Ubuntu 18.04 VM on our vSphere Cluster and configured the VM as described in the following documentation:
https://wiki.samba.org/index.php/Joining_a_Samba_DC_to_an_Existing_Active_Directory#Using_the_Domain_Controller_as_a_File_Server

The following packages are installed:
apt-get install samba krb5-user krb5-config winbind libpam-winbind libnss-winbind bind9

I'm trying to join the domain with the following command:
samba-tool domain join tyre24.local DC -U"tyre24.local\administrator" --dns-backend=BIND9_DLZ -d5

But the join fails with some errors as shown below ...


Here are (hopefully) all necessary configs and Logs ;)

Comment 1 Andrew Bartlett 2018-06-27 18:25:33 UTC
OK, so for others looking into this the secrets.tdb thing is a Red Herring and this is the same as this thread:

https://lists.samba.org/archive/samba-technical/2018-June/128752.html

The windows DC is rejecting our modify of the replication status of the application partition.  We may need to use a different API for that or do it a different way.

Joining to the naming master with --server may help.
Comment 2 Tim Herrmann (mail address dead) 2018-06-28 08:24:14 UTC
Hi Andrew,

thank you for you're response.

I've tried the join with the "--server" parameter to join directly over the naming-master but now I get a slighty different error message xD

According to the other issue, the only solution there was also to use the "--server" parameter, isn't it?

Comment 3 Andrew Bartlett 2018-06-28 08:35:02 UTC
For some reason the server has not detected the correct site via CLDAP, and so has defaulted to 'Default-First-Site-Name', which is not present in your domain. 

which sites are present?  do any cover the subnet of the new DC?

Do you have a Default-First-Site-Name (perhaps in another language?).
Comment 4 Tim Herrmann (mail address dead) 2018-06-28 08:49:48 UTC
You're right, there is no site named 'Default-First-Site-Name'.

Actually we only have 1 site defined in the forest wich is called "Siegelbach" and it covers the subnet 192.168.104.0/21.
All Windows DCs and the new SAMBA4 DC are in this subnet.
Comment 5 Björn Jacke 2019-09-18 11:26:50 UTC
renaming the default-first-site-name seems to be commonly supported in the Windows world, so samba-tool needs to be enhanced to look out for the right site name in any case. From comment#2 it seems like at least with the --server parameter the site name is not looked up or not used when creating the new DC account.

if you still have a chance to test this, can you have a look if the additional parameter --site=<sitename> makes the join work for you?
