[Samba] Join ad DC went wrong

I tried to promote another server as a domain controller so I can get my
machines upgraded to Debian 8

Conveniently the samba versions are the same

Can you please show us your smb.conf and /etc/hosts?


It seems your /etc/hosts resolve soothsayer.d.oflameo.com to 127.0.0.1 
instead of its real IP. See
https://wiki.samba.org/index.php/Join_a_domain_as_a_DC#Verify_.2Fetc.2Fhosts


Did you bind Samba to some of your interfaces and forgot to add 
localhost? See
https://wiki.samba.org/index.php/Samba_port_usage#Prevent_Samba_from_listening_on_all_interfaces

Marc

You caught it.

I had localhost.oflameo.com, but I didn't have localhost.
