=== SSSD 1.9.3 ===

The SSSD team is proud to announce the release of version 1.9.3 of
the System Security Services Daemon.

This release is mainly focused on fixing regressions in functionality
introduced by new features during the 1.9 development cycle or bugs in
the new features themselves.

As always, the source is available from https://fedorahosted.org/sssd

RPM packages will be made available for Fedora shortly, initially for F-18
and rawhide and later also backported to F-17. We will also provide test builds
for RHEL6.3 as was the case with 1.9.2.

== Feedback ==

Please provide comments, bugs and other feedback via the sssd-devel or
sssd-users mailing lists:
    https://lists.fedorahosted.org/mailman/listinfo/sssd-devel
    https://lists.fedorahosted.org/mailman/listinfo/sssd-users

== Highlights ==

* Many fixes related to deployments where the SSSD is running as a client
  of IPA server with trust relation established with an Active Directory server
* Multiple fixes related to correct reporting of group memberships,
  especially in setups that use nested groups
* Fixed a bug that prevented upgrade from the 1.8 series if the cache
  contained nested groups before the upgrade
* Restarting the responders is more robust for cases where the machine is
  under heavy load during back end restart
* The default_shell option can now be also set per-domain in addition to
  global setting
