yes, I change the parameter to allow zone transfers from the AD

Yes, I also read this information but I was hoping there was some other
solution to the issue. And I've done manually change the serial number of the
zone but without success

I'm a bit confused, so I tried to summarize your configuration. Please correct
me if I'm wrong:
zone "ejemplo.com" = hosted on AD server
zone "ejemplo.gob.ve" = hosted on FreeIPA server
What is your target? Do you want to have both zones on each server? I.e. one
server will be master for one zone and slave for the other zone (at the same
time)?
Zone transfers are supported from IPA 3.0. IPA can host only master zones,
slave zones have to be set in /etc/named.conf manually. There is no
centralized management of slave zones.
Generally, you can test zone-transfers with dig:
slave$ dig @master_IP -t AXFR zone.name
It should print something like:
zone.example. 86400 IN SOA unused-4-107.brq.redhat.com.
nonexistent.zone.example. 1344953446 123 123 666 1
zone.example. 86400 IN NS unused-4-107.brq.redhat.com.
zone.example. 86400 IN TXT "zone.example"
...
zone.example. 86400 IN SOA unused-4-107.brq.redhat.com.
nonexistent.zone.example. 1344953446 123 123 666 1
This way you can test ACL and other settings on master.
Does transfer with dig it work for both master servers?

Hi,
Is the zone not transferring at all, or is it just the updates that's
not transferred to the AD slave server?
If the zone is not transferring at all: Did yo modify the "Allow
transfer" property of the zone ?
If the updates is not transferring: I believe automatic increment of the
zone serial number will be supported in IPA 3.0. The IPA developers will
have to confirm that. However you can manually change the serial number
under Zone Settings.
Hope this helps.

Can you verify that managed entries are configured:
# ipa-managed-entries -l
It should return:
UPG Definition
NGP Definition
This enables user-private groups and netgroup-private groups.

I haven't tested this but you might try
--user-ignore-attribute=uidnumber,gidnumber.

The current user is available via: principal = getattr(context, 'principal')
Using this you can look up that user:
(binddn, bindattrs) = find_entry_by_attr("krbprincipalname", principal,
"krbPrincipalAux")

Folks,
Hopefully this isn't a dumb question, but I'm constrained by a few
things on my estate and would be looking to deploy something like the
following:
2 Datacentres
2 IPA servers at each datacentre
ipa1.domain.com <http://ipa1.domain.com> \_ datacentre A
ipa2.domain.com <http://ipa2.domain.com> /
ipa3.domain.com <http://ipa3.domain.com> \_ datacentre B
ipa4.domain.com <http://ipa4.domain.com> /
The datacentres are linekd, but bandwidth not great.
Client's in datacentre A should therefore use ipa1.domain.com
<http://ipa1.domain.com> and
ipa2.domain.com <http://ipa2.domain.com> as primary servers and only fail
over to ipa3 & ipa4
when both 1 & 2 are out of action. Clients would revert to using
ipa1/ipa2 whenever either of them came back online.
I understand this configuration has already been done as part of
https://fedorahosted.org/freeipa/ticket/2282
What I'm wondering is if I can force my clients to load balance
communication between ipa1 & ipa2.
I don't have the ability to use the _srv_ records in DNS as that's set
up for the AD servers on our network. I also can't create separate DNS
servers for the Linux estate (not that I'd particularly want to).
Is there any current configuration that I can use to force load
balancing between ipa1/ipa2 under ideal conditions. Falling back to
ipa2 when ipa1 is out of action. Falling back to (load balanced
perhaps?) ipa3/ipa4 when ipa1 & ipa2 are both out of action.
Hope the description is reasonable.
Thanks
