Please note that the latter is valid only for FreeIPA 3.3
and later. <br>
FreeIPA 3.0 does not support authentication over LDAP in the
compat tree.<br>

Ok. I will definitively use Kerberos. But looking at the
diagram of page 22 in <a href="http://www.freeipa.org/images/1/1e/Devconf2013-linux-ad-integration-options.pdf" target="_blank">http://www.freeipa.org/images/1/1e/Devconf2013-linux-ad-integration-options.pdf</a>
I see that SSSD in the GNU/Linux host is authenticating
against both Active Directory and FreeIPA. Does the email
server that I mentioned before, have to be configured in a
similar way that SSSD in the GNU/Linux host of the example? Or
is just enough that it is configured against the FreeIPA
Kerberos and nothing else?.<br>

You configure client (SSSD) to point to IPA but it will discover
that IPA is in trust relations and would know how to deal with
tickets coming from AD side.<br>
This is why there are two arrows. They show communication.<br></div></blockquote></div><br></div><div class="gmail_extra">Ok. And what about a mail server?. We are planning to use Zimbra, and we want that users from both FreeIPA and AD use it. Could we just configure it to authenticate against FreeIPA Kerberos?. Or do we have to make something else?.<br>
