Well..
still doing some test I found more evidence that the samba-tool domain
"samba-tool domain demote --remove-other-dead-server=" didnt work as
expected. 

If I query the internal dns I found the records of the old
domain controller: 

root@dc:~# samba-tool dns query dc.trust.local
trust.local serveribm.trust.local A -U administrador
Password for
[TRUSTadministrador]:
 Name=, Records=1, Children=0
 A: 192.168.0.66
(flags=f0, serial=1478, ttl=3600)

And if I ask for the
_ldap._tcp.trust.local record it points to the old domain controller.

#
dig -t SRV _ldap._tcp.trust.local
