[Samba] Setting up Second Samba DC samba-tool ntacl sysvolreset fails

Hi List!

I am working my way through getting familiar with samba and I have two
domain controllers now with an additional samba file server.
The servers are CentOS 7.4.1708;
 the domain controllers are built from source with samba-4.7.1;
 and the file server, installed winbind, smb and nmb from CentOS repos.

My problem is after bringing up the second domain controller and
successfully joining it to the domain, as the wiki directs I tried to
run samba-tool ntacl sysvolreset and this fails.

[root at testdc2 private]# samba-tool ntacl sysvolreset
open: error=2 (No such file or directory)
ERROR(runtime): uncaught exception - (-1073741823, '{Operation Failed}
The requested operation was unsuccessful.')

Please what am I doing wrong?

Have you added any other GPO's to your first DC ?
If so, you need to 'sync' them to the second DC.

You should remove the two lines above, you do not need them.

You need to add 'idmap_ldb:use rfc2307 = yes'

[Samba] Setting up Second Samba DC samba-tool ntacl sysvolreset fails

Hi Rowland

I removed the winbind lines, and added the 'idmap_ldb:use rfc2307 yes'
line to the second DC, and
rebooted the servers,  but the error does not go away.

First DC:
[global]
        dns forwarder = 8.8.8.8
        netbios name = TESTBOX
        realm = SAMDOM.TESTING.COM
        server role = active directory domain controller
        workgroup = SAMDOM
        idmap_ldb:use rfc2307 = yes
        log file = /var/log/samba/%m.log
        log level = 3
        tls enabled = yes

        template shell = /bin/bash
        template homedir = /share/%U

[netlogon]
        path = /usr/local/samba/var/locks/sysvol/samdom.testing.com/scripts
        read only = No

[sysvol]
        path = /usr/local/samba/var/locks/sysvol
        read only = No

Second DC:
[global]
        netbios name = TESTDC2
        realm = SAMDOM.TESTING.COM
        server role = active directory domain controller
        workgroup = SAMDOM
        idmap_ldb:use rfc2307 = yes
        tls enabled = yes

        template shell = /bin/bash
        template homedir = /share/%U


[netlogon]
        path = /usr/local/samba/var/locks/sysvol/samdom.testing.com/scripts
        read only = No

[sysvol]
        path = /usr/local/samba/var/locks/sysvol
        read only = No
