2009-12-11
- The SSSD's SSSDConfig python API is complete
- authconfig-6.0.0-1, currently built in Koji and awaiting a Rawhide compose, contains all of the GUI features necessary for configuring the SSSD, taking advantage of the SSSDConfig python API
- firstboot invokes authconfig with SSSD support when selecting "Use Network Login"
Still to do:
- Add SSSD to the default package set (pending FESCo approval of this Feature)
- Schedule a Test Day for configuring and testing this Feature

- SSSD has been added as a default package in the "core" package group in Comps.
2010-02-05
- All necessary packages are in place in comps, authconfig and SSSD are working together
- Note: There are plans to redesign the actual authconfig interface to be simpler for end-users, but this is not a condition for Feature complete.
Detailed Description
This feature would provide support in firstboot for joining a client to an LDAP/Kerberos or FreeIPA server. Users would be able to select "Use Network Login" during firstboot setup and configure it for connection to one or more central identity and authentication stores.
Benefit to Fedora
The prime benefit of the System Security Services Daemon is support for offline logins. Above and beyond the traditional pam_ldap or pam_krb5 approaches, the SSSD would remove the need for laptop users of Fedora to maintain a local account, separate from their centrally-managed account, to work offline or disconnected from the central servers.
Scope
The SSSD and its dependency packages (libtdb, libldb, libtevent, libtalloc and c-ares) need to be included in the default installation of Fedora. Support needs to be added to authconfig to provide a simplistic way to configure the SSSD. To that end, a python API is exposed from the SSSD that can be consumed by authconfig. Support for the new authconfig SSSD features needs to be added to firstboot.
How To Test
Testing will require a centralized identity and authentication store. The SSSD natively supports LDAP as an identity store, and either LDAP or Kerberos 5 as an authentication store. The SSSD has been tested successfully against FreeIPA (LDAP+Kerberos) as well as Fedora DS and MIT Kerberos, and limited testing against ActiveDirectory.
To test, one would need to configure the SSSD using authconfig to communicate with a centralized user store. Then they may attempt to log in using SSH or GDM (or KDM, etc.). If this succeeds, they can then attempt to do the same while offline.
If authenticating against a Kerberos server, they should also verify that they received a valid TGT (when performing online authentication).
User Experience
Users with centrally managed accounts will no longer need to maintain second, local user for use when not connected to the central servers.
Dependencies
At this time, no dependencies other than those listed above are known.
Contingency Plan
If it is not completed in time, Fedora can drop this feature with no ill effects and continue to use the existing remote authentication methods.
Documentation
Release Notes
Fedora 13 can now take advantage of the System Security Services Daemon to enable high-performance, cached authentication and identity lookups, as well as support for offline authentication.
Offline caching of identity data is supported for LDAP and FreeIPA servers, and offline authentication is supported for LDAP, Kerberos 5 and FreeIPA authentication servers.
