full_name_format and supplemental groups
by Orion Poplawski 26 Oct '16

26 Oct '16

Running IPA with an AD trust. Users are in AD. Trying to use full_name_format = %1$s to strip the domain from user names. This appears to break supplemental groups in strange ways. On the IPA server: Without full_name_format: # id orion(a)ad.nwra.com uid=470202603(orion(a)ad.nwra.com) gid=470202603(orion(a)ad.nwra.com) groups=470202603(orion(a)ad.nwra.com),470200513(domain users(a)ad.nwra.com),470204703(pirep rd users(a)ad.nwra.com),470204714(wireless access@ad.nwra.com),470204715(nwra-users@ad.nwra.com),470204701(boulder@ad.nwra.com),470207608(heimdall users(a)ad.nwra.com),470200512(domain admins(a)ad.nwra.com),470207124(andreas admins(a)ad.nwra.com) With: # id orion(a)ad.nwra.com uid=470202603(orion) gid=470202603(orion) groups=470202603(orion) If I add: default_domain_suffix = ad.nwra.com # id orion uid=470202603(orion) gid=470202603(orion) groups=470202603(orion),470200512(domain admins),470207608(heimdall users),470204714(wireless access),470204715(nwra-users),470204701(boulder),470204703(pirep rd users),470207124(andreas admins),470200513(domain users) Which I guess makes some sense as you'd need to add the domain suffix back on to find the groups. But this appears to completely break IPA clients (with full_name_format = %1$s and default_domain_suffix = ad.nwra.com) # id orion(a)ad.nwra.com id: orion(a)ad.nwra.com: no such user # id orion id: orion: no such user >From looking at the server logs, it looks like only the IPA domain is searched If I reset the server back to normal (drop full_name_format and default_domain_suffix): # id orion uid=470202603(orion) gid=470202603(orion) groups=470202603(orion) I don't get any supplemental groups.

netlink messages on Infiniband causing sssd to exit
by Ryan Novosielski 19 Aug '16

19 Aug '16

Over time, I’ve been having seemingly random sssd quits that I’ve not been able to figure out. Today, I finally traced it to fluctuations on my Infiniband fabric: sssd.log (Tue Nov 3 13:17:59 2015) [sssd] [message_type] (0x0200): netlink Message type: 16 (Tue Nov 3 13:17:59 2015) [sssd] [link_msg_handler] (0x1000): netlink link message: iface idx 4 (ib0) flags 0x1003 (broadcast,multicast,up) (Tue Nov 3 13:17:59 2015) [sssd] [message_type] (0x0200): netlink Message type: 16 (Tue Nov 3 13:17:59 2015) [sssd] [link_msg_handler] (0x1000): netlink link message: iface idx 4 (ib0) flags 0x11043 (broadcast,multicast,up,running,lower) This exactly corresponds to the time in /var/log/messages for the unexplained shutdown: 2015-11-03T13:17:59-05:00 node75 sssd[pam]: Shutting down 2015-11-03T13:17:59-05:00 node75 sssd[be[default]]: Shutting down 2015-11-03T13:17:59-05:00 node75 sssd[nss]: Shutting down Here is sssd_default.log for good measure: (Tue Nov 3 13:17:59 2015) [sssd[be[default]]] [sbus_remove_watch] (0x2000): 0x1414770/0x14133d0 (Tue Nov 3 13:17:59 2015) [sssd[be[default]]] [sbus_remove_watch] (0x2000): 0x1414770/0x13fef90 (Tue Nov 3 13:17:59 2015) [sssd[be[default]]] [be_ptask_destructor] (0x0400): Terminating periodic task [Cleanup of default] (Tue Nov 3 13:17:59 2015) [sssd[be[default]]] [sdap_handle_release] (0x2000): Trace: sh[0x14bd850], connected[1], ops[(nil)], ldap[0x1424260], destructor_lock[0], release_memory[0] (Tue Nov 3 13:17:59 2015) [sssd[be[default]]] [remove_connection_callback] (0x4000): Successfully removed connection callback.

As I know that Infiniband tends to flutter a little bit before the link comes up, I’m thinking this is probably the same cause.

please do not remove enumeration from AD provider

Please don't do this. Enumeration is a very useful feature. It allows us to do things like this: $ getent passwd | grep -i lastname The equivalent ldapsearch command is much more tedious: $ ldapsearch -z 0 -E pr=2147483647/noprompt -o ldif-wrap=no -L -L -H 'ldap:///dc%3Dexample%2Cdc%3Dorg -Y GSSAPI -N -b "dc=example,dc=org" "(&(objectClass=user)(cn=*lastname*))" dn cn sAMAccountName More generically, enumeration is the way Unix/Linux has always worked. Even getting users to change from: grep -i lastname /etc/passwd To this: getent passwd | grep -i lastname ...has been a struggle. We also have various services that (unfortuantely) pre-load the passwd and group files at startup by enumerating them with getpwent_r() and getgrent_r(), instead of using the get*nam_r() and get*id_r() functions as-needed. These services break outright if enumeration is disabled. (Yes, these services are broken. Yes, they shouldn't do that. But our ability to fix them is extremely limited at best, because we don't control them.) Finally, we have many systems that cannot be joined to Active Directory (for policy reasons, not technical reasons). But we want to use the same passwd/group entries on those systems as returned by sssd on hosts that are joined to Active Directory. We do this by scraping the output of "getent -s sss passwd" and "getent -s sss group" and manually merging it into the local passwd and group files (respectively) on these hosts. > It's just a legacy feature, so those who need it can fall back to > the LDAP provider.. But the LDAP provider doesn't support ID mapping; only the AD provider does. And ID mapping is the main reason we use sssd. I'm not asking you to make enumeration the default. It shouldn't be; it should be something you only turn on if you need it, and you KNOW you need it. But if you need it, you NEED it. Please don't take it away.

Announcing SSSD 1.13.1
by Jakub Hrozek 06 Jan '16

06 Jan '16

== SSSD 1.13.1 === The SSSD team is proud to announce the release of version 1.13.1 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 == * Initial support for Smart Card authentication was added. The feature can be activated with the new pam_cert_auth option * The PAM prompting was enhanced so that when Two-Factor Authentication is used, both factors (password and token) can be entered separately on separate prompts. At the same time, only the long-term password is cached, so offline access would still work using the long term password * A new command line tool sss_override is present in this release. The tools allows to override attributes on the SSSD side. It's helpful in environment where e.g. some hosts need to have a different view of POSIX attributes than others. Please note that the overrides are stored in the cache as well, so removing the cache will also remove the overrides * New methods were added to the SSSD D-Bus interface. Notably support for looking up a user by certificate and looking up multiple users using a wildcard was added. Please see the interface introspection or the design pages for full details * Several enhancements to the dynamic DNS update code. Notably, clients that update multiple interfaces work better with this release * This release supports authenticating againt a KDC proxy * The fail over code was enhanced so that if a trusted domain is not reachable, only that domain will be marked as inactive but the backed would stay in online mode * Several fixes to the GPO access control code are present == Packaging Changes == * The Smart Card authentication feature requires a helper process p11_child that needs to be marked as setgid if SSSD needs to be able to. Please note the p11_child requires the NSS crypto library at the moment * The sss_override tool was added along with its own manpage * The upstream RPM can now build on RHEL/CentOS 6.7 == Documentation Changes == * The config_file_version configuration option now defaults to 2. As an effect, this option doesn't have to be set anymore unless the config file format is changed again by SSSD upstream * It is now possible to specify a comma-separated list of interfaces in the dyndns_iface option * The InfoPipe responder and the LDAP provider gained a new option wildcard_lookup that specifies an upper limit on the number of entries that can be returned with a wildcard lookup * A new option dyndns_server was added. This option allows to attempt a fallback DNS update against a specific DNS server. Please note this option only works as a fallback, the first attempt will always be performed against autodiscovered servers. * The PAM responder gained a new option ca_db that allows the storage of trusted CA certificates to be specified * The time the p11_child is allowed to operate can be specified using a new option p11_child_timeout == Tickets Fixed ==

How do I disable SRV lookup?
by Ondrej Valousek 02 Dec '15

02 Dec '15

Hi list, How do I completely disable SRV lookups? This functionality is corrupted in SSSD so I wanted to disable it completely by defining ad servers explicitely: ad_server = myserver1, myserver2 ldap_uri = ldap://myserver1, ldap://myserver2 subdomains_provider = none ldap_use_tokengroups = False ad_domain = TEST.COM However, in logs I can still see the SRV plugin in action trying to populate AD servers automatically. Is it possible somehow?

sub attribute query....?
by Matthew Nicholson 21 Nov '15

21 Nov '15

So, I've got an....interesting problem... At a new gig, who has been using a product Centrify to do unix auth for systems for a while now (years and years). Now tha thte team is more built up, we want to move away from this as a number of us have done sssd + ldap+kerberos with AD a few times. However, centrify has done some odd things with user and group objects. The biggest issue of which is that 1). they are not normal person/user/group/posixgroup objects...2). they keep the most important attributes (uid, homedir, shell, etc). all stuffed info ONE attribute, "keywords". So, a ldap query of a user object ends up being this: <snip> objectClass: top objectClass: leaf objectClass: connectionPoint objectClass: serviceConnectionPoint cn: mn174 <snip> name: mn174 objectGUID:: Kq81FaqN50eFDZK9+57CZQ== keywords: shell:/bin/zsh keywords: gecos:Matthew Nicholson keywords: altGuid: keywords: uid:133859 keywords: unix_enabled:TRUE keywords: parentLink:S-1-5-21-1935655697-484061587-839522115-314656 keywords: home:/home/mn174 keywords: gid:2133859 </snip> So, right now while i COULD get sssd to find the object, I can't get it to pull out the important attributes like uid etc. Is there any way to tell sssd to do attribute sub-queries? basically "the uid is in keyword attribute, sub attribute uid" ? I'm less that pleased this product did such things. Thank full it does have a NIS server so worst case I'm going to dump all the users/groups and import into AD proper (which DOES have the same account/group info, just not with all the attributes @ the moment) .

sssd going offline & unable to recover after machine hard-reset
by Ondrej Valousek 20 Nov '15

20 Nov '15

Hi List, Just experiencing issue with a machine which needed to be hard-rebooted due to the NFS problems. After restart I noticed SSSD is unable to go online after message: [sdap_kinit_done] (0x0100): Could not get TGT: 14 [Bad address] [fo_set_port_status] (0x0100): Marking port 0 of server 'myserver' as 'not working' .... Do we know what could be wrong? Service sssd restart solves the issue. Can replicate on RHEL 6/7.

Announcing SSSD 1.13.2
by Jakub Hrozek 19 Nov '15

19 Nov '15

== SSSD 1.13.2 === The SSSD team is proud to announce the release of version 1.13.2 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 == * This is primarily a bugfix release, with minor features added to the local overrides feature * The sss_override tool gained new user-show, user-find, group-show and group-find commands * The PAM responder was crashing if PAM_USER was set to an empty string. This bug was fixed * The sssd_be process could crash when looking up groups in setups with IPA-AD trusts that use POSIX attributes but do not replicate them to the Global Catalog * A socket leak in case SSSD couldn't establish a connection to an LDAP server was fixed * SSSD's memory cache now behaves better when used by long-running applications such as system deamons and the administrator invalidates the cache * The SSSDConfig Python API no longer throws an exception when config_file_version is missing * The InfoPipe D-Bus interface is able to retrieve user groups correctly if the user is a member of non-POSIX groups like ipausers as well * Lookups by certificate now work correctly in multi-domain environment * The lookup of POSIX attributes after startup was relaxed to only check attribute presence, not validity. The POSIX check was also made less verbose * A bug when looking up a subdomain user by UPN users was fixed == Packaging Changes == * The memory cache for initgroups results was previously not packaged. This bug was fixed. * Python 2/3 packaging in the RPM specfile was improved == Tickets Fixed == https://fedorahosted.org/sssd/ticket/2176 warn if memcache_timeout is greater than entry_cache_timeout

Questions [maybe a bug] about SSSD non-anonymous binding working with LDAP
by aaron wang 14 Nov '15

14 Nov '15

Hi all, I'm configuring SSSD on a system to authenticate users against the LDAP server. LDAP server side: there are basically three options for the anonymous binding flag, 0 for completely disallow anonymous binding, 1 allows anonymous binding, 2 allows anonymous bind but allows only search operations on root DSE entry for anonymous users SSSD side: I'm providing the ldap_default_bind_dn and ldap_default_bind_authtok for the binding. Tests: 1) if admin changes the anonymous binding flag to "COMPLETELY DISALLOW" or "ONLY ALLOW DSE", the authentication against LDAP server doesn't work from the sssd log, the sssd has marked the LDAP server as "working", but the sssd can't find the user in ldap 2) if admin sets anonymous binding flag to "ALLOW ANONYMOUS BINDING", the authentication against LDAP server works The only difference between test 1) and test 2) is the anonymous binding flag. I'm expecting that if I provide binding dn and binding password in the sssd.conf, the server could turn off the anonymous completely or at least partially. Is there an known issue around this ? version: sssd-1.9.2 Thanks, Aaron
