sssd performance on large domains
by zfnoctis＠gmail.com 03 Feb '22

03 Feb '22

Hi, I'm wondering if there are any plans to improve sssd performance on large active directory domains (100k+ users, 40k+ groups), or if there are settings I am not aware of that can greatly improve performance, specifically for workstation use cases. Currently if I do not set "ignore_group_members = True" in sssd.conf, logins can take upwards of 6 minutes and "sssd_be" will max the CPU for up to 20 minutes after logon, which makes it a non-starter. The reason I want to allow group members to be seen is that I want certain domain groups to be able to perform elevated actions using polkit. If I ignore group members, polkit reports that the group is empty and so no one can elevate in the graphical environment. Ultimately this means that Linux workstations are at a severe disadvantage since they cannot be bound to the domain and have the normal set of access features users and IT expect from macOS or Windows. Distributions used: Ubuntu 16.04 (sssd 1.13.4-1ubuntu1.1), Ubuntu 16.10 (sssd 1.13.4-3) and Fedora 24 (sssd-1.13.4-3.fc24). All exhibit the same problems. I've also tried "ldap_group_nesting_level = 1" without seeing any noticeable improvement with respect to performance. Putting the database on /tmp isn't viable as these are workstations that will reboot semi-frequently, and I don't believe this is an I/O bound performance issue anyways. Thanks for your time.

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…

Does anyone use id_provider=local ?
by Jakub Hrozek 16 Oct '17

16 Oct '17

Hi, are there any SSSD users who actively use a configuration with: id_provider=local ? If so, what is your use-case? We're considering deprecating and eventually removing this provider upstream. The replacemant for id_provider=local would be id_provider=files: https://fedorahosted.org/sssd/wiki/DesignDocs/FilesProvider which is already under review and later extension of the SSSD's D-Bus interface to allow manipulating custom user attributes. My current plan for deprecating the local provider is to only build the provider and the tools around it if a configure-time flag is provided. This flag would be disabled by default. Then, if noone complains, eventually just remove the code.

SSSD Packet Capture Samples
by Tom Peterson 08 Aug '17

08 Aug '17

Hi All, First off thank you for all the hard work put into SSSD! It's been a great piece of software to work with and seems like it has a configuration setting for just about anything that can be thrown at it! We use SSSD at work and I've helped troubleshoot a few instances of authenticating against an external LDAP server. I setup a little lab to collect captures of some different config settings. My initial set is around different TLS scenarios: https://support.cloudshark.org/kb/sssd-activedirectory-captures.html All of the raw capture files can be downloaded after opening them by going to 'Export -> Download File'. I'll be adding to this and have a few more scenarios in mind I want to explore. If anyone has any feedback or suggestions on things they would like to see please let me know!I Hoping someone finds this little contribution of captures useful. And once again, thank you for all the work put into SSSD! -Tom

Announcing SSSD 1.15.3
by Jakub Hrozek 25 Jul '17

25 Jul '17

SSSD 1.15.3 =========== The SSSD team is proud to announce the release of version 1.15.3 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 ^^^^^^^^^^^^ * In a setup where an IPA domain trusts an Active Directory domain, it is now possible to define the domain resolution order (see http://www.freeipa.org/page/Releases/4.5.0#AD_User_Short_Names). Starting with this version, SSSD is able to read and honor the domain resolution order, providing a way to resolve Active Directory users by just their short name. SSSD also supports a new option "domain_resolution_order" applicable in the "[sssd]" section that allows to configure short names for AD users in setup with "id_provider=ad" or in a setup with an older IPA server that doesn't support the "ipa config-mod --domain-resolution-order" configuration option. Also, it is now possible to use "use_fully_qualified_names=False" in a subdomain configuration, but please note that the user and group output from trusted domains will always be qualified to avoid conflicts. * Design page - Shortnames in trusted domains <https://docs.pagure.org/SSSD.sssd/design_pages/shortnames.html> * SSSD ships with a new service called KCM. This service acts as a storage for Kerberos tickets when "libkrb5" is configured to use "KCM:" in "krb5.conf". Compared to other Kerberos credential cache types, KCM is better suited for containerized environments and because the credential caches are managed by a stateful daemon, in future releases will also allow to renew tickets acquired outside SSSD (e.g. with "kinit") or provide notifications about ticket changes. This feature is optional and can be disabled by selecting "--without-kcm" when configuring the SSSD build. * Design page - KCM server for SSSD <https://docs.pagure.org/SSSD.sssd/design_pages/kcm.html> * NOTE: There are several known issues in the "KCM" responder that will be handled in the next release such as issues with very large tickets <https://pagure.io/SSSD/sssd/issue/3386> or tracking the SELinux label of the peer <https://pagure.io/SSSD/sssd/issue/3434> or even one intermittent crash <https://pagure.io/SSSD/sssd/issue/3454> There are also some differences between how SSSD's KCM server works compared to Heimdal's KCM server such as visibility of ccaches by root <https://pagure.io/SSSD/sssd/issue/3376>. * Support for user and group resolution through the D-Bus interface and authentication and/or authorization through the PAM interface even for setups without UIDs or Windows SIDs present on the LDAP directory side. This enhancement allows SSSD to be used together with apache modules <https://github.com/adelton/mod_lookup_identity> to provide identities for applications * Design page - Support for non-POSIX users and groups <https://docs.pagure.org/SSSD.sssd/design_pages/non_posix_support.html> * SSSD ships a new public library called "libsss_certmap" that allows a flexible and configurable way of mapping a certificate to a user identity. This is required e.g. in environments where it is not possible to add the certificate to the LDAP user entry, because the certificates are issued externally or the LDAP schema cannot be modified. Additionally, specific matching rules allow a specific certificate on a smart card to be selected for authentication. * Design page - Matching and Mapping Certificates <https://docs.pagure.org/SSSD.sssd/design_pages/matching_and_mapping_certifi…> * The Kerberos locator plugin can be disabled using an environment variable "SSSD_KRB5_LOCATOR_DISABLE". Please refer to the "sssd_krb5_locator_plugin" manual page for mode details. * The "sssctl" command line tool supports a new command "user-checks" that enables the administrator to check whether a certain user should be allowed or denied access to a certain PAM service. * The "secrets" responder now forwards requests to a proxy Custodia back end over a secure channel. Notable bug fixes ^^^^^^^^^^^^^^^^^ * The IPA HBAC evaluator no longer relies on "originalMemberOf" attributes to construct the list of groups the user is a member of. Maintaining the "originalMemberOf" attribute was unreliable and was causing intermittent HBAC issues. * A bug where the cleanup operation might erroneously remove cached users during their cache validation in case SSSD was set up with "enumerate=True" was fixed. * Several bugs related to configuration of trusted domains were fixed, in particular handling of custom LDAP search bases set for trusted domains. * Password changes for users from trusted Active Directory domains were fixed Packaging Changes ----------------- * A new KCM responder was added along with a manpage. The upstream reference specfile packages the responder in its own subpackage called "sssd-kcm" and a krb5.conf snippet that enables the "KCM" credentials cache simply by installing the subpackage * The "libsss_certmap" library was packaged in a separate package. There is also a "libsss_certmap-devel" subpackage in the upstream packaging. Documentation Changes --------------------- * "sssd-kcm" and "libsss_certmap" are documented in their own manual pages. * A new option "domain_resolution_order" was added. This option allows to specify the lookup order (especially w.r.t. trusted domains) that sssd will follow. Please see the Shortnames in trusted domains <https://docs.pagure.org/SSSD.sssd/design_pages/shortnames.html> design page. for mode details. * New options "pam_app_services" and "domain_type" were added. These options can be used to only limit certain PAM services to reach certain SSSD domains that should only be exposed to non-OS applications. For more details, refer to the Support for non-POSIX users and groups <https://docs.pagure.org/SSSD.sssd/design_pages/non_posix_support.html> design page. * The "secrets" responder supports several new options related to TLS setup and handling including "verify_peer", "verify_host", "capath", "cacert" and "cert". These options are all described in the "sssd-secrets" manual page.

Samba NT_STATUS_WRONG_PASSWORD when using IP Address
by Marc-Henri Pamiseux 25 Jul '17

25 Jul '17

Hi sssd user's, I contacted yesterday the Samba discussion list about a malfunction with this software. I was asked to put my question to the sssd list, which I do :) You will find below the email sent to the Samba list: ************************************************************************** I've update a domain member smb server to samba 4.6.5. I don't want to use winbind for this upgrade so i'm trying with sssd. After a long informative reading on this subject, i've finaly success to connect using the hostname. The domain member is well join to AD-DC : # net ads testjoin Join is OK Another test : # adcli info -D local.mydomain [domain] domain-name = local.mydomain domain-short = MYDOMAIN domain-forest = local.mydomain domain-controller = hera.local.mydomain domain-controller-site = Laval domain-controller-flags = pdc gc ldap ds kdc timeserv closest writable good-timeserv full-secret domain-controller-usable = yes domain-controllers = hera.local.mydomain [computer] computer-site = Laval From the Domain member server (RHEA), i can view the main sharing using my account but not when using the administrator account. By the way, i belive i made some limitation on this account because nobody have to use this one # smbclient -L //RHEA -U myident Enter MYDOMAIN\myident's password: Sharename Type Comment --------- ---- ------- IPC$ IPC IPC Service (Samba 4.6.5-Debian) projets Disk Gestion des projets public Disk Public Stuff myident Disk Repertoire Personnel Domain=[MYDOMAIN] OS=[] Server=[] Server Comment --------- ------- RHEA Samba 4.6.5-Debian Workgroup Master --------- ------- MYDOMAIN RHEA From the AD-DC server (HERA), i can see the same thing using my account. Stil on the AD-DC, i've try another method : # smbclient -L //192.168.1.2 -U myident Enter MYDOMAIN\myident's password: Domain=[MYDOMAIN] OS=[] Server=[] Sharename Type Comment --------- ---- ------- IPC$ IPC IPC Service (Samba 4.6.5-Debian) projets Disk Gestion des projets public Disk Public Stuff myident Disk Repertoire Personnel Domain=[MYDOMAIN] OS=[] Server=[] Server Comment --------- ------- RHEA Samba 4.6.5-Debian Workgroup Master --------- ------- MYDOMAIN RHEA Well... Everything seems to work. Now i want to test an access from a windows client. I have open the session on the domain using my account. Now i open windows explorer and i type //RHEA in the address bar. I can see the share that i can use. So, why do i post on this mailing list ? Because when I use address //192.168.1.2, the operating system asks me to identify myself. But i'have already done this when i've open this session. I am surprised because it is usually the opposite error that occurs. Let's go to the log on RHEA Host (192.168.1.2) : [2017/07/25 02:46:15.286177, 0] ../source3/auth/auth_domain.c:226(domain_client_validate) domain_client_validate: unable to validate password for user myident in domain MYDOMAIN to Domain controller HERA.LOCAL.MYDOMAIN. Error was NT_STATUS_WRONG_PASSWORD. [2017/07/25 02:46:15.288928, 2] ../source3/auth/auth.c:315(auth_check_ntlm_password) check_ntlm_password: Authentication for user [myident] -> [myident] FAILED with error NT_STATUS_WRONG_PASSWORD [2017/07/25 02:46:15.296364, 2] ../auth/gensec/spnego.c:768(gensec_spnego_server_negTokenTarg) SPNEGO login failed: NT_STATUS_WRONG_PASSWORD Ok, but this error occurred even before I specified an identifier. I removed the Windows-based workstation from the domain and then, i join it again. In this regard, i have noticed that a computer can not join a Windows Active Directory domain if the Netbios over TCP / IP option is not enabled. Too bad ! RSAT is installed on this computer and i still can login and maintain Active Directory and DNS zone from this computer. But now, i cannot see RHEA share anymore. I've got the same error even if i use IP or hostname. sssd seems to work fine because the command getent passwd give me a result : # getent passwd myident myident:*:1072:513:Marc-Henri Pamiseux:/home/MYDOMAIN/myident:/bin/bash Does someone can help me to investigate ? ************************************************************************** Thanks in advance. -- Marc-Henri Pamiseux - SARL Libricks - www.libricks.fr 6 rue Léonard de Vinci - CS 20119, 53001 LAVAL Cedex Tel. : 02.30.96.15.24 / Mobile : 06.26.71.30.97

Autofs Entries Caching
by Douglas Duckworth 25 Jul '17

25 Jul '17

Hi We have autofs working great with sssd thanks to support of this listserv. Though during testing we noticed that only home directories, for users who had previously logged into a given server, were cached by the sssd client. Can sssd cache autofs for all users in our directory even if they haven't recently logged into a server? Here's our current config for autofs portion: autofs_provider = ldap ldap_autofs_search_base = ou=autofs.maps,cn=server,ou=machines,dc=blah ldap_autofs_map_master_name = autofs.maps ldap_autofs_map_object_class = automountMap ldap_autofs_entry_object_class = automount ldap_autofs_map_name = ou ldap_autofs_entry_key = cn ldap_autofs_entry_value = automountInformation ldap_deref = always Thanks Doug Thanks, Douglas Duckworth, MSc, LFCS HPC System Administrator Scientific Computing Unit Physiology and Biophysics Weill Cornell Medicine E: doug(a)med.cornell.edu O: 212-746-6305 F: 212-746-8690

2008AD and uidNumber, gidNumber mapping on CentOS7 with sssd
by Jelle de Jong 20 Jul '17

20 Jul '17

Hello everybody, I been trying hard to get sssd to work on a new CentOS 7 workstation. sssd --version 1.14.0 # working ldapsearch command and output https://paste.fedoraproject.org/paste/L3Uv8Mg6FMuLlIHXkL5~0Q/raw The problem is I am at a customer that has an old Windows 2008 AD server with Unix tools and the uidNumber, gidNumber, unixHomeDirectory and loginShell need to be used, so that my nfs shares have the correct mapping. They used an old NIS server in the passed but it is broken and has no AD connection any more. I can not seem to bind to the RootDSE without using a username and password, see the ldapsearch command, i tried converting the "LDAP(a)wdm.local" to a cn path, but whatever i try i get a " additional info: 80090308: LdapErr: DSID-0C0903A8, comment: AcceptSecurityContext error, data 52e, v1db1" back. My sssd just keeps loging: ([sssd[be[default]]] [dp_req_reply_gen_error] (0x0080): DP Request [Subdomains #0]: Finished. Target is not supported with this configuration. [root@vsxtest01 ~]# cat /etc/sssd/sssd.conf [domain/default] id_provider = ldap auth_provider = ldap chpass_provider = ldap ldap_uri = ldap://sw008.wdm.local/ ldap_search_base = ou=COMPANY,dc=wdm,dc=local #ldap_schema = rfc2307bis #ldap_user_home_directory = unixHomeDirectory #ldap_tls_reqcert = allow #ldap_id_use_start_tls = True ldap_tls_cacertdir = /etc/openldap/cacerts debug_level = 5 autofs_provider = ldap #ldap_default_bind_dn = cn=LDAP,ou=Users,ou=COMPANY,dc=wdm,dc=local ldap_default_bind_dn = LDAP(a)wdm.local ldap_default_authtok = *secret* ldap_default_authtok_type = password cache_credentials = True [sssd] config_file_version = 2 services = autofs domains = default [autofs] I have no idea how to get my user authentication working with the correct uidNumber, gidNumber mapping. Can somebody maybe help? Kind regards, Jelle de Jong
