One-way trust is the default now, use 'trust add --two-way ' to force bidirectional trust https://fedorahosted.org/freeipa/ticket/4959 In case of one-way trust we cannot authenticate using cross-realm TGT against an AD DC. We have to use trusted domain object from within AD domain and access to this object is limited to avoid compromising the whole trust configuration. Instead, IPA framework can call out to oddjob daemon and ask it to run the script which can have access to the TDO object. This script (com.redhat.idm.trust-fetch-domains) is using cifs/ipa.master principal to retrieve TDO object credentials from IPA LDAP if needed and then authenticate against AD DCs using the TDO object credentials. The script pulls the trust topology out of AD DCs and updates IPA LDAP store. Then IPA framework can pick the updated data from the IPA LDAP under normal access conditions.

IPA Server
Overview
--------
FreeIPA allows Linux administrators to centrally manage identity,
authentication and access control aspects of Linux and UNIX systems
by providing simple to install and use command line and web based
managment tools.
FreeIPA is built on top of well known Open Source components and standard
protocols with a very strong focus on ease of management and automation
of installation and configuration tasks.
FreeIPA can seamlessly integrate into an Active Directory environment via
cross-realm Kerberos trust or user synchronization.
Benefits
--------
FreeIPA:
* Allows all your users to access all the machines with the same credentials
and security settings
* Allows users to access personal files transparently from any machine in
an authenticated and secure way
* Uses an advanced grouping mechanism to restrict network access to services
and files only to specific users
* Allows central management of security mechanisms like passwords,
SSH Public Keys, SUDO rules, Keytabs, Access Control Rules
* Enables delegation of selected administrative tasks to other power users
* Integrates into Active Directory environments
Components
----------
The FreeIPA project provides unified installation and management
tools for the following components:
* LDAP Server - based on the 389 project (LDAP)
http://directory.fedoraproject.org/wiki/Main_Page
* KDC - based on MIT Kerberos implementation
http://k5wiki.kerberos.org/wiki/Main_Page
* PKI based on Dogtag project
http://pki.fedoraproject.org/wiki/PKI_Main_Page
* Samba libraries for Active Directory integration
http://www.samba.org/
* DNS Server based on BIND and the Bind-DynDB-LDAP plugin
