sssd/0008-TESTS-Add-integration-tests-for-the-auto_private_gro.patch
Lukas Slebodnik 1dedfbb334 Resolves: upstream#3523 - ABRT crash - /usr/libexec/sssd/sssd_nss in setnetgrent_result_timeout 
Resolves: upstream#3588 - sssd_nss consumes more memory until restarted
                          or machine swaps
Resolves: failure in glibc tests
          https://sourceware.org/bugzilla/show_bug.cgi?id=22530
Resolves: upstream#3451 - When sssd is configured with id_provider proxy and
                          auth_provider ldap, login fails if the LDAP server
                          is not allowing anonymous binds
Resolves: upstream#3285 - SSSD needs restart after incorrect clock is
                          corrected with AD
Resolves: upstream#3586 - Give a more detailed debug and system-log message
                          if krb5_init_context() failed
Resolves: rhbz#1431153 - SSSD ships a drop-in configuration snippet
                         in /etc/systemd/system
Backport few upstream features from 1.16.1
