Re: [Samba] Joining Samba4 to existing AD




Hi guys,

I changed my /etc/hosts and looks like this:


[root@lim-inf1-dns-02 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4
localhost4.localdomain4
::1         localhost localhost.localdomain localhost6
localhost6.localdomain6
10.3.251.19      dc-01.example.com  dc-01
172.28.240.252  dc-02.example.com  dc-02



So, to be clear, dc-01.example.com is the Windows AD hostname.
dc-02.example.com is the linux machine itself

I tried to join domain again but it is pretty the same error :(


[root@ldc-02 ~]# samba-tool domain join EXAMPLE.COM DC -UAdministrator
