| Others domains : DOMAINB, DOMAINC (domain controllers DCB y DCC)

It should be obtaining a service for DCC$@DOMAINC.  That's
probably what you are seeing.

Generally it is not needed.  Certainly not when all the
domains are AD and the Samba host is configured with
'security = ads'.

| 3) My krb5.conf doesn 't contain any references to
| servers. All it contains is dns_lookup_realm=true,
| dns_lookup_kdc=true and default_realm=XXXXX. Do I
| need anything specific or current krb5 can obtain everything
| it needs from the DNS?

DNS is fine.  That's how I run.  Make sure that the appropriate
SRV records are in DNS though.

| 4) Do I need to do the ktpass thing at the windows DC?

Nope.  It is all handled by the AD trusts.

Hope this helps.

cheers, jerry
