Alexander Bokovoy 23a49538f1 ipa-print-pac: acquire and print PAC record for a user 
Helper utility to investigate PAC content of users in trusted
environments. Supports direct ticket acquisition and S4U2Self protocol
transition.

1. Direct ticket acquisition

In direct ticket acquisition mode the utility first does one of the
following actions:
 - obtain a TGT ticket for a user principal using supplied password
 - import existing TGT from a default credentials cache

Once a user TGT is available, the utility will attempt to acquire a service
ticket to a service which key is specified in a keytab (default or
passed with --keytab option) and simulate establishing context to the
service application.

If establishing context succeeds, MS-PAC content of the service ticket
will be printed out.

2. S4U2Self protocol transition

In protocol transition case a service application obtains own TGT using
a key from the keytab and then requests a service ticket to itself in
the name of the user principal, performing S4U2Self request.

If accepting this service ticket succeeds, MS-PAC content of the service
ticket will be printed out.

If KDC does not support or rejects issuing MS-PAC record for a user, an
error message 'KDC has no support for padata type' will be printed.

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:
