[Freeipa-users] Announcing SSSD 1.13.4

I am plagued by the "sssd dereference processing failed : Input/output error" problem. Is there any news when this version of sssd will be released for RedHat/Centos?

My current version is: 1.12.4-47.el6

Subject: [Freeipa-users] Announcing SSSD 1.13.4

                        == SSSD 1.13.4 ===

The SSSD team is proud to announce the release of version 1.13.4 of the System Security Services Daemon.

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

RPM packages will be made available for Fedora shortly.

== 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 ==
    * The IPA sudo provider was reimplemented. The new version reads the
      data from IPA's LDAP tree (as opposed to the compat tree populated by
      the slapi-nis plugin that was used previously). The benefit is that
      deployments which don't require the compat tree for other purposes,
      such as support for non-SSSD clients can disable those autogenerated
      LDAP trees to conserve resources that slapi-nis otherwise requires. There
      should be no visible changes to the end user.
    * SSSD now has the ability to renew the machine credentials (keytabs)
      when the ad provider is used. Please note that a recent version of
      the adcli (0.8 or newer) package is required for this feature to work.
    * The automatic ID mapping feature was improved so that the administrator
      is no longer required to manually set the range size in case a RID in
      the AD domain is larger than the default range size
    * A potential infinite loop in the NFS ID mapping plugin that was
      resulting in an excessive memory usage was fixed
    * Clients that are pinned to a particular AD site using the ad_site
      option no longer communicate with DCs outside that site during service
      discovery.
    * The IPA identity provider is now able to resolve external
      (typically coming from a trusted AD forest) group members during
      get-group-information requests. Please note that resolving external
      group memberships for AD users during the initgroup requests used to
      work even prior to this update. This feature is mostly useful for cases
      where an IPA client is using the compat tree to resolve AD trust users.
    * The IPA ID views feature now works correctly even for deployments
      without a trust relationship. Previously, the subdomains IPA provider
      failed to read the views data if no master domain record was created
      on the IPA server during trust establishment.
    * A race condition in the client libraries between the SSSD closing
      the socket as idle and the client application using the socket was
      fixed. This bug manifested with a Broken Pipe error message on the
      client.
    * SSSD is now able to resolve users with the same usernames in different
      OUs of an AD domain
    * The smartcard authentication now works properly with gnome-screensaver

== Packaging Changes ==
    * The krb5.include.d directory is now owned by the sssd user and
      packaged in the krb5-common subpackage

== Documentation Changes ==
    * A new option ldap_idmap_helper_table_size was added. This option can
      help tune allocation of new ID mapping slices for AD domains with a high
      RID values. Most deployments can use the default value of this option.
    * Several PAM services were added to the lists that are used to map
      Windows logon services to Linux PAM services. The newly added PAM
      services include login managers (lightdm, lxdm, sddm and xdm) as well
      as the cockpit service.
    * The AD machine credentials renewal task can be fine-tuned using
      the ad_machine_account_password_renewal_opts to change the initial
      delay and period of the credentials renewal task. In addition, the new
      ad_maximum_machine_account_password_age option allows the administrator
      to select how old the machine credential must be before trying to
      renew it.
    * The administrator can use the new option pam_account_locked_message to
      set a custom informational message when the account logging in is locked.
