For a proper SASL bind with GSSAPI against an AD LDAP server a PAC is needed. To allow SSSD in ipa_server_mode to access the LDAP or GC server of a trusted domain with the credentials of a FreeIPA server host a PAC must be added to the TGT for the host. We use the well know RID of the Domain Computers group (515) for the primary gid element of the PAC, this is the same as AD uses for host tickets. The rid element of the PAC is set to the well know RID of the Domain Controllers group (516). This is working for the SSSD use case but might be improved later for more general use cases. To determine if a host is a FreeIPA server or not it is checked if there is an entry for the host in cn=master,cn=ipa,cn=etc,$base. Unfortunately this requires an additional LDAP lookup. But since TGS-REQs for hosts should be rare I think it is acceptable for the time being. Fixes https://fedorahosted.org/freeipa/ticket/3651
IPA Server
What is it?
-----------
For efficiency, compliance and risk mitigation, organizations need to
centrally manage and correlate vital security information including:
* Identity (machine, user, virtual machines, groups, authentication
credentials)
* Policy (configuration settings, access control information)
* Audit (events, logs, analysis thereof)
Since these are not new problems. there exist many approaches and
products focused on addressing them. However, these tend to have the
following weaknesses:
* Focus on solving identity management across the enterprise has meant
less focus on policy and audit.
* Vendor focus on Web identity management problems has meant less well
developed solutions for central management of the Linux and Unix
world's vital security info. Organizations are forced to maintain
a hodgepodge of internal and proprietary solutions at high TCO.
* Proprietary security products don't easily provide access to the
vital security information they collect or manage. This makes it
difficult to synchronize and analyze effectively.
