Enumerate users from external group from AD trust
by Bolke de Bruin 29 Nov '19

29 Nov '19

Hello, I have sssd 1.13.00 working against FreeIPA 4.2 domain. This domain has a trust relationship with a active directory domain. One of the systems we are using requires to enumerate all users in groups by (unfortunate) design (Apache Ranger). This is done by using “getent group”. During this enumeration the full user list for a group that has a nested external member group* is not always returned so we thought to add “getent group mygroup” in order to get more details. Unfortunately this does not seem to work consistently: sometimes this gives information sometimes it does not: [root@master centos]# getent group ad_users ad_users:*:1950000004: [root@master centos]# id bolke(a)ad.local UID=1796201107(bolke(a)ad.local) GID=1796201107(bolke(a)ad.local) groepen=1796201107(bolke(a)ad.local),1796200513(domain users@ad.local),1796201108(test@ad.local) [root@master centos]# getent group ad_users ad_users:*:1950000004:bolke@ad.local <mailto:bolke@ad.local> If I clear the cache (sss_cache -E) the entry is gone again: [root@master centos]# getent group ad_users ad_users:*:1950000004: My question is how do I get sssd to enumerate *all users* in a group consistently? Thanks! Bolke * https://docs.fedoraproject.org/en-US/Fedora/18/html/FreeIPA_Guide/trust-gro…

'no primary group ID provided' when trying to use ldap mode against AD
by Daniel Hermans 24 Apr '17

24 Apr '17

Hi, i'd like to use sssd in ldap mode against Active Directory so I have defined: id_provider = ldap auth_provider = ldap Yes krb5 would be better but i only have a BIND account and cannot add computer objects. This 'should' be possible - it works with nslcd. As I don't have Posix attributes i'm using: ldap_id_mapping = true fallback_homedir = /home/%d/%u default_shell = /bin/bash sssd can bind with LDAPS and can seem to get user info from the domain: (Fri Aug 26 13:34:10 2016) [sssd[be[dev]]] [sdap_process_message] (0x4000): Message type: [LDAP_RES_SEARCH_ENTRY] (Fri Aug 26 13:34:10 2016) [sssd[be[dev]]] [sdap_parse_entry] (0x1000): OriginalDN: [CN=Some User,OU=Admin Accounts,DC=dev,DC=somedomain,DC=com].

Ignoring. Have tried against two different domains with identical result ( one a cleanly installed 2012R2 domain ). Any ideas what I'm doing wrong? Is this possible? Various (old) posts suggests it is. This was first (incorrectly) posted to sssd-devel, Jakub Hrozek updated and told me to define ldap_idmap_default_domain_sid so sssd no longer reports this: (Fri Aug 26 13:34:10 2016) [sssd[be[dev]]] [sdap_save_user] (0x0400): SID S-1-5-21-3970895924-989261097-3267629119-1443 does not belong to any known domain Thanks in advance!!

Hi, Can you help me with a problem I struggle quite a time, that appeared after upgrade to sssd-13.4 (Ubuntu Xenial): User can not login; Home directory (nfs) secured with Kerberos, is mounted, with proper idmapping, but user is refused to login to the desktop (lightdm). Ssh login is possible, but permission denied to access the home directory. This is setup with: .. id_provider=ad use_fully_qualified_names = true ldap_id_mapping = false ..

Question about AD authentication and trusts
by Guy Knights 21 Nov '16

21 Nov '16

Hi, Can anyone confirm for me if SSSD supports authentication of users belonging to a trusted domain via an AD controller in the trusting domain? ie. A user attempts to log in as fred(a)test1.example.com on a client machine running SSSD, where SSSD has joined a domain test2.example.com and there is a 2-way forest trust between both domains. Is this supported? I've been trying to do so and so far it hasn't been working. For the record, my setup is: AD controller domain test1: Windows server 2012 R2 AD controller domain test2: Windows server 2012 R2 Ubuntu 14.04 client running SSSD 1.12.5 Thanks, Guy

sssd.conf and /var/lib/sss/db/config.ldb
by Daniel Hermans 09 Nov '16

09 Nov '16

Hi, not sure if a bug or not but a quick warning that hopefully may save someone some time! We use puppet to install sssd based on a condition. we: - yum install -y sssd - authconfig --enablesssd --enablesssdauth --enablelocauthorize --enableldap --enableldapauth --enablemkhomedir --enablecachecreds --update ( to setup PAM and nsswitch - not sure if ALL of these are necessary? ) - copy over our private config ( as you can't do all of the config with authconfig that i can see? ) This didn't work - intermittently sssd was using a 'stale' config. After much headbutting issue was twofold: - sssd is started and activated by the authconfig command, this creates config.ldb and cache_default.ldb - puppet writes the config file immediately and sssd restarted - sssd compares modification time of /etc/sssd/sssd.conf with /var/lib/sss/db/config.ldb and, because the times are the same ( written in the same minute ), IT IGNORES the new config file Solution: - add a '--nostart' to the authconfig to stop the initial start, this will prevent creation of the cache. Copy over the config and then start/enable ( which will create the cache ). Not sure if related but there is a TODO in the code around this area (src/confdb/confdb_setup.c) ret = sss_ini_get_mtime(init_data, sizeof(timestr), timestr); if (ret <= 0 || ret >= (int)sizeof(timestr)) { DEBUG(SSSDBG_FATAL_FAILURE, "Failed to convert time_t to string ??\n"); ret = errno ? errno : EFAULT; } /* FIXME: Determine if the conf file or any snippet has changed * since we last updated the confdb or if some snippet was * added or removed. */ Puppet then

Announcing SSSD 1.14.2
by Jakub Hrozek 07 Nov '16

07 Nov '16

=== SSSD 1.14.2 === The SSSD team is proud to announce the release of version 1.14.2 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 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 == * Several more regressions caused by cache refactoring to use qualified names internally were fixed, including a regression that prevented the krb5_map_user option from working correctly. * A regression when logging in with a smart card using the GDM login manager was fixed * SSSD now removes the internal timestamp on startup cache when the persistent cache is removed. This enables admins to follow their existing workflow of just removing the persistent cache and start from a fresh slate * Several fixes to the sssd-secrets responder are present in this release * A bug in the autofs responder that prevented automounter maps from being returned when sssd_be was offline was fixed * A similar bug in the NSS responder that prevented netgroups from being returned when sssd_be was offline was fixed * Disabling the netlink integration can now be done with a new option disable_netlink. Previously, the netlink integration could be disabled with a sssd command line switch, which is being deprecated in this release. * The internal watchdog no longer kills sssd processes in case time shifts during sssd runtime * The fail over code is able to cope with concurrent SRV resolution requests better in this release * The proxy provider gained a new option proxy_max_children that allows the administrator to control the maximum number of child helper processes that authenticate users with auth_provider=proxy * The InfoPipe D-Bus responder exports the UUIDs of user and group objects through a uniqueID property == Packaging Changes == * The private pipe directory permissions were changed from 0700 to 0750. The restrictive permissions we causing SELinux dac_override denials * The Python packages for python2 were renamed from python-package to python2-package with backwards-compatible Provides and Obsoletes * The sssd-common subpackage contains a new manual page sssd-secrets(5) * The sssd-tools subpackage explicitly Requires /sbin/service on platforms that don't support systemd in order to be able to restart sssd from the sssctl tool == Documentation Changes == * The kill_service option that was no longer useful after we moved from in-process pings to watchdog was removed * The --disable-netlink sssd(8) command-line option was removed in favor of [sssd] section option disable_netlink * The proxy_max_children option was added. Please see the highlights section for more details. * The sssd-secrets responder gained a man page in this release. * Two new options containers_nest_level and max_secrets options were added to the sssd-secrets responder. The former allows the administrator to configure the maximum nesting level of secrets containers, the latter allows the administrator to configure the maximum number of secrets that can be stored. Please note that both option apply to the local secrets provider only. * The sssd-ldap man page didn't specify different default for user and group name LDAP attribute default for the AD provider. This documentation bug was fixed. == Tickets Fixed == https://fedorahosted.org/sssd/ticket/2813 man page for sss_override command provides irrelevant information for --debug option https://fedorahosted.org/sssd/ticket/2841 sssd stores and returns incorrect information about empty netgroup (ldap-server: 389-ds) https://fedorahosted.org/sssd/ticket/3051 Move the diag_cmd option so that it's usable by the watchdog. https://fedorahosted.org/sssd/ticket/3052 Remove the no longer used kill_service command https://fedorahosted.org/sssd/ticket/3053 The sssd-secrets responder needs a manpage https://fedorahosted.org/sssd/ticket/3054 Create integration tests for the sssd-secrets responder https://fedorahosted.org/sssd/ticket/3056 The sssctl tool should restart the service with systemd's dbus API https://fedorahosted.org/sssd/ticket/3107 Python SSSD Config API deletes an item during iteration https://fedorahosted.org/sssd/ticket/3123 Netgroup resolution doesn't work offline https://fedorahosted.org/sssd/ticket/3125 secrets responder throws an internal error when trying to delete a non-existent secret https://fedorahosted.org/sssd/ticket/3127 SSSD qualifies principal twice in IPA-AD trust if the principal attribute doesn't exist on the AD side https://fedorahosted.org/sssd/ticket/3128 throw away the timestamp cache if re-initializing the persistent cache https://fedorahosted.org/sssd/ticket/3134 sssd is not able to authenticate with alias https://fedorahosted.org/sssd/ticket/3137 secrets: creating a secret in a container doesn't work https://fedorahosted.org/sssd/ticket/3140 autofs map resolution doesn't work offline https://fedorahosted.org/sssd/ticket/3142 expose disabling the netlink support as a sssd.conf option https://fedorahosted.org/sssd/ticket/3143 selinux avc denial for vsftp login as ipa user https://fedorahosted.org/sssd/ticket/3145 Update sssd-sudo man page to reflect native sudo support https://fedorahosted.org/sssd/ticket/3154 sssd exits if clock is adjusted backwards after boot https://fedorahosted.org/sssd/ticket/3163 resolving IPA nested user group is broken in 1.14 https://fedorahosted.org/sssd/ticket/3165 login using gdm calls for gdm-smartcard when smartcard authentication is not enabled https://fedorahosted.org/sssd/ticket/3167 SECRETS: Deleting a container that has children should fail https://fedorahosted.org/sssd/ticket/3168 secrets: Add a configurable depth limit for containers https://fedorahosted.org/sssd/ticket/3172 Access denied for user when access_provider = krb5 is set in sssd.conf https://fedorahosted.org/sssd/ticket/3173 unable to create group in sssd cache https://fedorahosted.org/sssd/ticket/3174 Clock skew makes SSSD return System Error https://fedorahosted.org/sssd/ticket/3175 sss_groupshow does not work https://fedorahosted.org/sssd/ticket/3178 unable to add local user in sssd to a group in sssd https://fedorahosted.org/sssd/ticket/3179 sss_override fails to export https://fedorahosted.org/sssd/ticket/3180 sss_cache -r option does not print error message if more than one argument is supplied https://fedorahosted.org/sssd/ticket/3181 libwbclient-sssd: update interface to version 0.13 https://fedorahosted.org/sssd/ticket/3184 sss_groupshow <user> fails with error "No such group in local domain.

LDAP TLS problem
