Highlights
----------
 * It is now possible to configure certain parameters of a trusted domain
   in a configuration file sub-section. In particular, it is now possible
   to configure which Active Directory DCs the SSSD talks to with a
   configuration like this::

    [domain/ipa.test]
    # IPA domain configuration. This domain trusts a Windows domain win.test

    [domain/ipa.test/win.test]
    ad_server = dc.win.test

 * Several issues related to socket-activating the NSS service, especially
   if SSSD was configured to use a non-privileged userm were fixed.
   The NSS service now doesn't change the ownership of its log files to
   avoid triggering a name-service lookup while the NSS service is not
   running yet. Additionally, the NSS service is started before any other
   service to make sure username resolution works and the other service
   can resolve the SSSD user correctly.

 * A new option "cache_first" allows the administrator to change the way
   multiple domains are searched. When this option is enabled, SSSD will
   first try to "pin" the requested name or ID to a domain by searching
   the entries that are already cached and contact the domain that contains
   the cached entry first. Previously, SSSD would check the cache and the
   remote server for each domain. This option brings performance benefit
   for setups that use multiple domains (even auto-discovered trusted
   domains), especially for ID lookups that would previously iterate over
   all domains. Please note that this option must be enabled with care as the
   administrator must ensure that the ID space of domains does not overlap.

 * The SSSD D-Bus interface gained two new methods:
   "FindByNameAndCertificate" and "ListByCertificate". These methods
   will be used primarily by IPA and
   `mod_lookup_identity <https://github.com/adelton/mod_lookup_identity/>
   to correctly match multple users who use the same certificate for Smart
   Card login.

 * A bug where SSSD did not properly sanitize a username with a newline
   character in it was fixed.

Packaging Changes
-----------------
None in this release

Documentation Changes
---------------------
 * A new option "cache_first" was added. Please see the Highlights
   section for more details

 * The "override_homedir" option supports a new template expansion "l"
   that expands to the first letter of username


Tickets Fixed
-------------
Please note that due to a bug in the pagure.io tracker, some tickets that
have dependencies set to other tickets cannot be closed at the moment.

 * <https://pagure.io/SSSD/sssd/issue/3317> - Newline characters (\n) must be sanitized before LDAP requests take place
 * <https://pagure.io/SSSD/sssd/issue/3316> - sssd-secrets doesn't exit on idle 
 * <https://pagure.io/SSSD/sssd/issue/3314> - sssd ignores entire groups from proxy provider if one member is listed twice 
 * <https://pagure.io/SSSD/sssd/issue/3164> - when group is invalidated using sss_cache dataExpireTimestamp entry in the domain and timestamps cache are inconsistent 
 * <https://pagure.io/SSSD/sssd/issue/2668> - [RFE] Add more flexible templating for override_homedir config option 
 * <https://pagure.io/SSSD/sssd/issue/2599> - Make it possible to configure AD subdomain in the server mode 
 * <https://pagure.io/SSSD/sssd/issue/3322> - chown in ExecStartPre of sssd-nss.service hangs forever 
 * <https://pagure.io/SSSD/sssd/issue/843>  - Login time increases strongly if more than one domain is configured 
 * <https://pagure.io/SSSD/sssd/issue/2320> - use the sss_parse_inp request in other responders than dbus
