Re: [Freeipa-users] Re: Auto create NFS home folders on IPA Server.

Two remaining questions. 1) Creating the NFS user folders on the server itself is not a problem however I would like to trap events that indicate USER logged into a client host. On this event, a home directory could then be created on the FreeIPA side. Without such an event I can't precreate it. So when a user logs into a client machine, is there any SSSD call initiated to the FreeIPA server that would show up in a log for example that I could in turn use to run a small shell script to precreate the user's home folder, if it doesn't exist? 2) Is there a way to get SSSD to retrieve the unixHomeDirectory that's defined in the UNIX Attribute on the AD side? Would be handy if I want to control all home directory locations on the AD side. The override_homedir works to force a folder but when I try the %o option to override_homedir, it appears to take the FreeIPA default home directory, not the AD one.

nsupdate
by Roger Martensson 13 Mar '18

13 Mar '18

Hi! Setup: Ubuntu 18.04 (future), SSSD 1.16.0, nsupdate/bind: 9.11.2.P1, 2008R2 DC/DNS I need some help and guidance with troubleshooting nsupdate-problems. I get the famous "TSIG error with server: tsig verify failure" when trying to update my A-record against our Microsoft DNS. I get the error in sssd-logs and the same error when running nsupdate manually with the same input as found in the logs (when cranking up debug level). I have tried with client keytab and with a user that I know have permission to update. (nsupdate with -g) SSSD is fully configured and I can do user lookups and logins. ldapsearch agains different domains in the forest with -Y GSSAPI works without problem. Our setup is a domain forest where the clients are in the subdomain and the DNS is in the parent domain. Parent DNS domain and subdomains is in the same Zone and has Secure Only updates enabled. Anyone have any ideas what I can do next to troubleshoot this issue?

Is it possible to disable or override hbac rules?
by Orion Poplawski 13 Mar '18

13 Mar '18

I'm dealing with a buggy sssd 1.13.4 on ubuntu 16.04 breaking HBAC rule processing for AD users. Is there someway I can disable this or override it for a specific user on the machine itself? Thanks. -- Orion Poplawski Manager of NWRA Technical Systems 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 https://www.nwra.com/

Announcing SSSD 1.16.1
by Jakub Hrozek 13 Mar '18

13 Mar '18

SSSD 1.16.1 =========== The SSSD team is proud to announce the release of version 1.16.1 of the System Security Services Daemon. The tarball can be downloaded from https://releases.pagure.org/SSSD/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 ————— New Features ^^^^^^^^^^^^ * A new option ``auto_private_groups`` was added. If this option is enabled, SSSD will automatically create user private groups based on user's UID number. The GID number is ignored in this case. Please see https://docs.pagure.org/SSSD.sssd/design_pages/auto_private_groups.html for more details on the feature. * The SSSD smart card integration now supports a special type of PAM conversation implemented by GDM which allows the user to select the appropriate smrt card certificate in GDM. Please refer to https://docs.pagure.org/SSSD.sssd/design_pages/smartcard_multiple_certifica… for more details about this feature. * A new API for accessing user and group information was added. This API is similar to the tradiional Name Service Switch API, but allows the consumer to talk to SSSD directly as well as to fine-tune the query with e.g. how cache should be evaluated. Please see https://docs.pagure.org/SSSD.sssd/design_pages/enhanced_nss_api.html for more information on the new API. * The ``sssctl`` command line tool gained a new command ``access-report``, which can generate who can access the client machine. Currently only generating the report on an IPA client based on HBAC rules is supported. Please see https://docs.pagure.org/SSSD.sssd/design_pages/attestation_report.html for more information about this new feature. * The ``hostid`` provider was moved from the IPA specific code to the generic LDAP code. This allows SSH host keys to be access by the generic LDAP provider as well. See the ``ldap_host_*`` options in the ``sssd-ldap`` manual page for more details. * Setting the ``memcache_timeout`` option to 0 disabled creating the memory cache files altogether. This can be useful in cases there is a bug in the memory cache that needs working around. Performance enhancements ^^^^^^^^^^^^^^^^^^^^^^^^ * Several internal changes to how objects are stored in the cache improve SSSD performance in environments with large number of objects of the same type (e.g. many users, many groups). In particular, several useless indexes were removed and the most common object types no longer use the indexed ``objectClass`` attribute, but use unindexed ``objectCategory`` instead (#3503) * In setups with ``id_provider=ad`` that use POSIX attributes which are replicated to the Global Catalog, SSSD uses the Global Catalog to determine which domain should be contacted for a by-ID lookup instead of iterating over all domains. More details about this feature can be found at https://docs.pagure.org/SSSD.sssd/design_pages/uid_negative_global_catalog.… Notable bug fixes ^^^^^^^^^^^^^^^^^ * A crash in ``sssd_nss`` that might have happened if a list of domains was refreshed while a NSS lookup using this request was fixed (#3551) * A potential crash in ``sssd_nss`` during netgroup lookup in case the netgroup object kept in memory was already freed (#3523) * Fixed a potential crash of ``sssd_be`` with two concurrent sudo refreshes in case one of them failed (#3562) * A memory growth issue in ``sssd_nss`` that occured when an entry was removed from the memory cache was fixed (#3588) * Two potential memory growth issues in the ``sssd_be`` process that could have hit configurations with ``id_provider=ad`` were fixed (#3639) * The ``selinux_child`` process no longer crashes on a system where SSSD is compiled with SELinux support, but at the same time, the SELinux policy is not even installed on the machine (#3618) * The memory cache consistency detection logic was fixed. This would prevent printing false positive memory cache corruption messages (#3571) * SSSD now remembers the last successfuly discovered AD site and use this for DNS search to lookup a site and forest during the next lookup. This prevents time outs in case SSSD was discovering the site using the global list of DCs where some of the global DCs might be unreachable. (#3265) * SSSD no longer starts the implicit file domain when configured with ``id_provider=proxy`` and ``proxy_lib_name=files``. This bug prevented SSSD from being used in setups that combine identities from UNIX files together with authentication against a remote source unless a files domain was explicitly configured (#3590) * The IPA provider can handle switching between different ID views better (#3579) * Previously, the IPA provider kept SSH public keys and certificates from an ID view in its cache and returned them even if the public key or certificate was then removed from the override (#3602, #3603) * FleetCommander profiles coming from IPA are applied even if they are assigned globally (to ``category: ALL``), previously, only profiles assigned to a host or a hostgroup were applied (#3449) * It is now possible to reset an expired password for users with 2FA authentication enabled (#3585) * A bug in the AD provider which could have resulted in built-in AD groups being incorrectly cached was fixed (#3610) * The SSSD watchdog can now cope better with time drifts (#3285) * The ``nss_sss`` NSS module's return codes for invalid cases were fixed * A bug in the LDAP provider that prevented setups with id_provider=proxy and auth_provider=ldap with LDAP servers that do not allow anonymous binds from working was fixed (#3451) Packaging Changes ----------------- * The FleetCommander desktop profile path now uses stricter permissions, 751 instead of 755 (#3621) * A new option ``--logger`` was added to the ``sssd(8)`` binary. This option obsoletes old options such as ``--debug-to-files``, although the old options are kept for backwards compatibility. * The file ``/etc/systemd/system/sssd.service.d/journal.conf`` is not installed anymore In order to change logging to journald, please use the ``--logger`` option. The logger is set using the ``Environment=DEBUG_LOGGER`` directive in the systemd unit files. The default value is ``Environment=DEBUG_LOGGER=--logger=files`` Documentation Changes --------------------- There are no notable documentation changes such as options changing default values etc in this release.

SSSD kerberos problem in multiple AD domains
by Roger Martensson 12 Mar '18

12 Mar '18

Hi! It's me again with multiple domain problems. :) I have once again problems with multiple domain. This time with login. Maybe some one of you could explain to me what I did wrong this time. OS: Ubuntu 17.10 SSSD: 1.15.3 Domain setup. two subdomain both connected to the same parent domain Both subdomains contains users. Most of them only contains one domain but some is found in both. Client is connected to subdomain1. I can login with a user on subdomain 1. When login in to subdomain2 (both using 'su-with-password-prompt' and 'ssh-to-localhost') I get a System Error 4. The log krb_child.log (which sssd_domain.log points to) I see these logs. (altered some names)

Apache/php integration
by Ondrej Valousek 12 Mar '18

12 Mar '18

Hi all, I see there is a new client API available for sssd 1.16. Is it possible to integrate it somehow with Apache/php? I.e. example: I authenticate user via mod_auth_gssapi obtaining username (and possibly TGT) so I need to lookup user's email address, say....

Experiencing a bug on users' name and ID
by Asif Iqbal 08 Mar '18

08 Mar '18

I have 300 out of 3000 users whose /home/<username> dir shows uid and gid instead of username and groupname. It seems to be behaving like a bug As soon I become a user with `sudo su - username' the uid of the home dir changes to username but gid still does not change to groupname. I also get an error message, but still successfully become that user $ ls -ld /home/mbniels drwx------. 3 80974 80974 4096 Feb 27 02:15 /home/mbniels $ su - mbniels Last login: Tue Feb 27 02:34:04 UTC 2018 on pts/39 /usr/bin/id: cannot find name for group ID 80974 groups: cannot find name for group ID 80974 $ ls -ld /home/mbniels drwx------. 3 mbniels 80974 4096 Feb 27 02:15 /home/mbniels Then to check the groups of username I get another error which then gets cleared by next command. $ groups mbniels mbniels : groups: cannot find name for group ID 80974 80974 users $ getent group mbniels mbniels:*:80974 $ groups mbniels mbniels : mbniels users It also fixes the gid to groupname $ ls -ld /home/mbniels/ drwx------. 3 mbniels mbniels 4096 Feb 27 02:15 /home/mbniels/ I noticed it reverts after may be within half an hour, not exact sure when. Almost behaves like `quantum entanglement'. As soon as I try to check by trying to become that user the issue disappears. This is not just cosmetic issue, when the home dir shows ownership with uid, instead of username, the user fails some commands. We just started noticing today, since we just built this box and only few months ago and users are being invited to start using this server Some annoying error it is showing like below and user then fails to ssh $ ssh remote No user exists for uid 80974 I am using centos 7 and sssd 1.15.2 $ cat /etc/redhat-release CentOS Linux release 7.4.1708 (Core) $ sssd --version 1.15.2 Here are some relevant logs https://paste.fedoraproject.org/paste/gBaZ-Vr8Urh-M5ABpaRNuA Appreciate any help -- Asif Iqbal PGP Key: 0xE62693C5 KeyServer: pgp.mit.edu A: Because it messes up the order in which people normally read text.

cached users
by Roger Martensson 05 Mar '18

05 Mar '18

Hi! OS: Ubuntu 16.04, SSSD: 1.13.4 I'm seeing something that has me wondering if I have missunderstood anything. (quite possible) I have multi domain Active Directory forest. I have a client connected to subdomain1 using SSSD and can do ID-query in both subdomain1 and subdomain2. If I have a user with a username that only exists in one of these domains then there is no problem. But if I have a user that exist with the same userid in both domain then queries looks strange to me. It seems that the first query gets cached and reused when querying the same userid in the other domain. For example. Query user 'simpleuser(a)subdomain1.domain.tld'. When I query 'simpleuser(a)subdomain2.domain.tld' I get the same result as the first query where it should be different. I'm using 'default_domain_suffix' in [sssd] section of the sssd.conf which adds 'use_fully_qualified_names'. I thought these settings would help but I can't see any changes. What am I missing? This is for me not a big problem but we do have some usecases where the same userid can exist on both subdomains.

Account locked message w/ OpenLDAP and ppolicy
by Kopera, Jeffrey M 05 Mar '18

05 Mar '18

Hi, I am having some issues trying to configure sssd to print out a message informing a user if their account is locked out. I thought it would be as simple as setting pam_account_locked_message, but I guess not. I suspect this is an sssd issue, but I suppose it could be a PAM issue. Here is what my sssd.conf file looks like: [domain/default] debug_level = 8 cache_credentials = True ldap_search_base = ************* ldap_user_search_base = ************* ldap_user_name = cn ldap_group_search_base = ************** id_provider = ldap auth_provider = ldap chpass_provider = ldap ldap_uri = ***************** ldap_tls_cacert = ******************** ldap_referrals = False enumerate = False access_provider = ldap ldap_access_order = ppolicy [sssd] services = nss, pam, autofs, ssh config_file_version = 2 domains = default [nss] homedir_substring = /home [pam] pam_verbosity = 3 pam_account_locked_message = "Account locked" [sudo] [autofs] [ssh] [pac] [ifp] And the relevant sections of PAM #%PAM-1.0 # This file is auto-generated. # User changes will be destroyed the next time authconfig is run. auth required pam_env.so auth sufficient pam_fprintd.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 100 quiet auth sufficient pam_sss.so use_first_pass auth required pam_deny.so account required pam_unix.so account sufficient pam_localuser.so account sufficient pam_succeed_if.so uid < 100 quiet account [default=bad success=ok user_unknown=ignore] pam_sss.so account required pam_permit.so I see the following message in the sssd log with a locked out account logging in: (Thu Mar 1 22:05:23 2018) [sssd[be[default]]] [sdap_op_add] (0x2000): New operation 1 timeout 6 (Thu Mar 1 22:05:23 2018) [sssd[be[default]]] [sdap_process_result] (0x2000): Trace: sh[0x1231d90], connected[1], ops[0x1303b50], ldap[0x12d0010] (Thu Mar 1 22:05:23 2018) [sssd[be[default]]] [simple_bind_done] (0x2000): Server returned control [1.3.6.1.4.1.42.2.27.8.5.1].

autofs in a AD-forest
by Roger Martensson 02 Mar '18

02 Mar '18

Hi! I'm experiencing something that I'm not sure is as expected or not. First some data: OS: Ubuntu 16.04 SSSD Version: 1.13.4 I have managed to set up a SSSD against a AD-subdomain. NSS-lookup works. Can use 'userid', 'userid(a)subdomain1.domain.tld' and UPN when looking up an ID. I have set up a auto_home hierarchy in AD on subdomain1.domain.tld and managed to get AutoFS to work using this and get a working homedirectory using autofs and NFS. When I do this with a user in an another subdomain in the forest (subdomain2.domain.tld) I get into trouble. ID-lookup works like a charm. I have also set up a auto_home-hierarchy in this other subdomain. When looking in the logs is looks like the implementation of autofs only uses the domain the SSSD is connected to. Not a single mention in the logs about the other subdomain regarding to autofs. Is it correct to assume that autofs in multiple domains in a forest doesn't work or am I doing something wrong? My sssd.conf looks like this. (some names have been changed to protect the innocent) [domain/subdomain1.domain.tld] access_provider = ad ad_domain = subdomain1.domain.tld ad_hostname = client1.subdomain1.domain.tld autofs_provider = ad cache_credentials = True debug_level = 8 default_shell = /bin/bash fallback_homedir = /userhome/%u id_provider = ad krb5_realm = SUBDOMAIN1.DOMAIN.TLD krb5_store_password_if_offline = True ldap_id_mapping = False mkhomedir = false realmd_tags = manages-system joined-with-adcli [sssd] config_file_version = 2 domains = subdomain1.domain.tld services = nss,pam,autofs
