SSSD 2.2.3

Highlights

New features

  • allow_missing_name now treats empty strings the same as missing names.
  • ‘soft_ocsp’ and ‘soft_crl options have been added to make the checks for revoked certificates more flexible if the system is offline.
  • Smart card authentication in polkit is now allowed by default.
  • ssh_use_certificate_matching_rules now allows no_rules and all_rules values (see man page for description).

Notable bug fixes

  • Fixed several memory management errors that caused SSSD to crash under some circumstances.
  • Handling of FreeIPA users and groups containing ‘@’ sign now works.
  • Issue when autofs was unable to mount shares was fixed.
