[sssd PR#758][opened] krb5_locator: always use port 88 for master KDC

Better use the default port 88 always for master KDC lookups. This patch also updates the man page for the locator plugin which was quite outdated.

[sssd PR#762][opened] responder: fix domain lookup refresh timeout
by sumit-bose 27 Feb '19

URL: https://github.com/SSSD/sssd/pull/762 Author: sumit-bose Title: #762: responder: fix domain lookup refresh timeout Action: opened PR body: """ Currently the timeout to check for new domains is reset whenever there is a request with an unknown domain name. If those requests happen more then once a minute (the default timeout) the timeout is always reset before it can expire and as a result the domain list is never refreshed. If SSSD starts offline with an empty domain list the NSS responder might never be able to resolve sub-domain users or groups even if the backend has switched to the online state and already refreshed the domain list.

Design Document: Change password without Password Modify Extended Operation
by Pavel Březina 20 Feb '19

20 Feb '19

https://pagure.io/SSSD/docs/pull-request/77 .. highlight:: none Change password on LDAP server that does not support Password Mofify Extended Operation ======================================================================================= Related ticket(s): ------------------ https://pagure.io/SSSD/sssd/issue/1314 Problem statement ----------------- Some directory servers either do not support Password Mofify Extended Operation (OID 1.3.6.1.4.1.4203.1.11.1, RFC 3062) for password change or this feature is disabled by default. SSSD is unable to perform password change on such servers. Even though we recommend to upgrade to servers that supports this feature, there are still users that will benefit from SSSD being able to change password without it. Use cases --------- * A user wants to change his/her password against LDAP that does not support Password Modify Extended Operation. Overview of the solution ------------------------ Provide new configuration option ``ldap_pwmodify_exop`` that will default to true (use extended operation for password change). If this options is set to false, SSSD will use simple LDAP modify operation instead of extended operation. Implementation details ---------------------- When a password change is requested, ``sdap_pam_chpass_handler_send`` is called. This request first authenticates the user with current password and then in ``sdap_pam_chpass_handler_auth_done`` tries to change it with extended operation by calling ``sdap_exop_modify_passwd_send``. At this point we should check the value of ``ldap_pwmodify_exop`` option and decide whether to continue with extended operation or use ``ldap_modify_ext`` instead. Information on how to change the password using simple LDAP modify operation can be found `here <https://www.ibm.com/support/knowledgecenter/SSVJJU_6.3.0/com.ibm.IBMDS.doc/…>`_ Configuration changes --------------------- * New option: ``ldap_pwmodify_exop`` How To Test ----------- Set ``ldap_pwmodify_exop`` to false and try to change user's password.

fleet commander integration
by Levin Stanislav 18 Feb '19

18 Feb '19

Hello, I want to ask you about design of fleet commander integration, which I found on https://docs.pagure.org/SSSD.sssd/design_pages/fleet_commander_integration.…. > The JSON files will be stored in a new directory owned by the > |sssd-ipa| subpackage. The top-level directory could be at > |/var/lib/sss/deskprofile/| with per-user subdirectories. So each > per-user JSON file would be stored at > |/var/lib/sss/deskprofile/<domain>/<username>/<profilename>.json|. The > |<username>| directories need to be owned by the user being logged in. > /var/lib/sss/deskprofile/<domain>/<username>/<profilename>.json > ------------ -------- ---------- ------------------ > | | | | > v | | | > Created by sssd package as | | | > root:root (or sssd:sssd) | | | > and has permissions 0751 | | | > | | | > v | | > Owned by user:user_group | | > and has permissions 0751 | | > | | > | | > v | > Owned by user:user_group | > and has permissions 0700 | > | > v > Owned by user:user_group > and has permissions 0400 As I see FleetCommander is executed with root privileges (without CAPs dropping) and is allowed to read user profiles. Why is "user" owner of the directory "<username>"? and why should we grant "user" with any permissions for this path? Why is it not just 0700 for dirs, 0400 for profiles, owner root/sssd_user for all subpaths? Could you please explain? Thank you in advance!
