Announcing SSSD 1.12.2
by Jakub Hrozek 20 Oct '14

20 Oct '14

=== SSSD 1.12.2 === The SSSD team is proud to announce the release of version 1.12.2 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 21 and rawhide 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 == * Fixed a regression where the IPA provider didn't fetch User Private Groups correctly * An important bug in the GPO access control which resulted in a wrong principal being used was fixed * Several new options are available for deployments that need to restrict a certain PAM service from connecting to a certain SSSD domain. For more details, see the description of pam_trusted_users and pam_public_domains options in the sssd.conf(5) man page and the domains option in the pam_sss(8) man page. * When SSSD is acting as an IPA client in setup with trusted AD domains, it is able to return group members or full group memberships for users from trusted AD domains. Please note that this feature requires a recent (4.1 Alpha or newer) release of FreeIPA server * Suport for the 'views' feature of IPA. Please note that this feature requires a recent (4.1 Alpha or newer) release of FreeIPA server. Additionally, this feature will be improved in future versions of SSSD. == Packaging Changes == * Some unit tests depend on nss_wrapper and uid_wrapper libraries. These dependencies are optional, if the libraries are not detected during build, the tests are skipped == Documentation Changes == * New PAM responder options pam_trusted_users and pam_public_domains options * New pam_sss module option called domains * A new template expansion %U that expands into the user's User Principal Name * The default value of ldap_user_objectsid and ldap_group_objectsid changed from "Not set" to objectSID in the LDAP provider == Tickets Fixed == https://fedorahosted.org/sssd/ticket/1021 [RFE] Add domains= option to pam_sss https://fedorahosted.org/sssd/ticket/1644

[PATCH] SSSD: Add the options to specify a UID and GID to run as
by Jakub Hrozek 20 Oct '14

20 Oct '14

Hi, I guess I can safely send another round of patches that were already tested by Michal and me. The first patch adds new command line options --uid and --gid to all SSSD servers, making it possible to switch to another user ID if needed. So far all the servers still run as root. The other patches are trivial refactoring for unit tests (2 and 3). I don't like the #ifdefs in server.c, but I couldn't think of another way.. The final patch is a unit test for server_setup, exercising different options.

[PATCHES] IPA: Use libsemanage
by Michal Židek 20 Oct '14

20 Oct '14

Hi, these 3 patches remove the old approach where we directly wrote the selinux login file. Here, the same approach is used as in the tools (sss_useradd/sss_usermod) where we already use libsemanage to manage these tasks. The advantage is that we remove some lines of code (yay!) and get the auditing of selinux user changes for free. 1st patch just moves stuff around, so that set_seuser function can be used from IPA provider. 2nd patch is a very simple change that adds new attribute to the set_seuser function (mls_range). The main functionality is in the 3rd patch. Note that to test the patch, you must run in permissive mode. $ setenforce Permissive Otherwise you will get AVC denials (because sssd_be is not allowed to use libsemanage). So we will have to change the selinux policy in fedora/rhel to make it work this way. I will ping the selinux policy maintainer after the patches are reviewed. Patches are attached. Thanks, Michal

[PATCHES] IFP: support views
by Pavel Březina 20 Oct '14

20 Oct '14

Since the NSS and PAM parts of the views are in the review process and I don't expect any big changes there, I'm sending IFP part. It depends on Sumit's patches.
