Alexander Bokovoy 443a99060c ipa-kdb: use entry DN to compare aliased entries in S4U operations
When working with aliased entries, we need a reliable way to detect
whether two principals reference the same database entry. This is
important in S4U checks.

Ideally, we should be using SIDs for these checks as S4U requires PAC
record presence which cannot be issued without a SID associated with an
entry. This is true for user principals and a number of host/service
principals associated with Samba. Other service principals do not have
SIDs because we do not allocate POSIX IDs to them in FreeIPA. When PAC
is issued for these principals, they get SID of a domain computer or
domain controller depending on their placement (IPA client or IPA
server).

Since 389-ds always returns unique entry DN for the same entry, rely on
this value instead. We could have used ipaUniqueID but for Kerberos
principals created through the KDB (kadmin/kdb5_util) we don't have
ipaUniqueID in the entry.

FreeIPA Server

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 management 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:
