Re: [Samba] Joining Samba4 to existing AD




Correct you need a smb.conf. 

https://wiki.samba.org/index.php/User_Documentation 

 

And please do correct your hosts file before you join. 

 

>>  127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 dc-02.example.com dc-02 << NOT GOOD 

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

10.3.251.19                    dc-01.example.com  dc-01  << CORRECT
