Rob Crittenden 3ab3578b36 On password reset also set krbLastAdminUnlock to unlock account
This fixes the case where an account is locked on one or more servers
and the password is reset by an administrator. The account would
remain locked on those servers for the duration of the lockout.

This is done by setting krbLastAdminUnlock to the current date and
time. The lockout plugin will see this and unlock the account. Since
the value should be replicated along with the password any server
that has the new password will also be unlocked.

This does incur an additional attribute that must be replicated,
whether it is needed or not, but since lockout is computed
per-server this is the only guaranteed way to be sure that the
account will be unlocked everywhere.

My original thought was to grab password replication events and detect
whether the user was locked out and unlock them. On any given server
you can only know if the user is locked out on that server by
computing it. Doing this would require generalizing the lockout code
so it could be computed on password change. krbLastFailedAuth could
be wiped which would unlock the account on that master (the attribute
is not replicated by default).

So it is complexity vs additional replication. Assuming that admin
reset is relatively rare let's start with that. This doesn't lock
us into this solution for the future.

We could set this attribute on user-driven password changes as
well but the original ask and my thinking are that if you forgot
your password and got locked out, how can you change it yourself?
Upon reflection I guess a user could fat-finger it a bunch of times
against one IPA server then have a revelation and log in against a
different server. So they would still be locked out for the duration
on the first one. I'm not sure the extra replication is worth it for
user-generated password changes or that users would be saavy enough
to try another server for the change.

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:
