Hi,

Let's see if any of the questions gets answered or at least I get
ponte dto something that can help me.

I followed this wiki:
http://wiki.samba.org/index.php/Samba4/HOWTO/Join_a_domain_as_a_DC#Getting_ready_for_joining_Samba_as_a_DC_to_an_existing_domain

I have my S4 domain running, I compiled and installed another S4 to
replicate the first server and joined successfully to the domain but
replication seems to be broken.

Commandused:

Seemed to have succeded, then I radn the recommended tests

These testes run from the BDC seem to work.

host -t CNAME ad828198-a723-44c2-8d7f-d5f801e2849f._msdcs.mundo.local
ad828198-a723-44c2-8d7f-d5f801e2849f._msdcs.mundo.local is an alias

Did you AT LEAST search the mailing list???????
Check if ping (or any program using GLIBC's *NSS* DNS resolver) can
resolve your 7106cbf4-3cf6-4ed9-b019-dd937035b1e7._msdcs.mundo.local name

Yes I searched the ML with no luck.

Yes, I did and it works, I had to add7106cbf4-3cf6-4ed9-b019-dd937035b1e7._msdcs.mundo.loca lto /etc/hostsand it works.


So I thinks it's a DNS issue.

Thanks for your answer.

I tried to check replication status but this error shows
