Re: [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
