sssd pam authentication works with su, but not ssh
by rpoyner＠wisc.edu 29 Aug '16

29 Aug '16

I'm using sssd 1.11.7 in a jail on freebsd 10.2. and seeing an odd failure. sssd is configured for nss, and pam both against an openldap server. Nss seems to work as evidenced by various getent calls. When I ssh to the jail as an ldap user the authentication fails with return code 9: (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_print_data] (0x0100): command: PAM_AUTHENTICATE (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_print_data] (0x0100): domain: default (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_print_data] (0x0100): user: myuser (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_print_data] (0x0100): service: sshd (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_print_data] (0x0100): tty: not set (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_print_data] (0x0100): ruser: not set (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_print_data] (0x0100): rhost: host.edu (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_print_data] (0x0100): authtok type: 1 (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_print_data] (0x0100): newauthtok type: 0 (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_print_data] (0x0100): priv: 1 (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_print_data] (0x0100): cli_pid: 65873 (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_dom_forwarder] (0x0100): pam_dp_send_req returned 0 (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_dp_process_reply] (0x0100): received: [9][default] (Thu Aug 25 10:55:52 2016) [sssd[pam]] [pam_reply] (0x0200): pam_reply called with result [9].

autofs question
by Thomas Beaudry 26 Aug '16

26 Aug '16

Hi Everyone, I am trying to do the following and haven't been able to find a resource on it so I wanted to know if it's even possible. Here is what I want to be able to do. 1. ssh to server (I have and AD credentials check working with sssd already) 2. automount a directory from a NAS on ssh login with sssd. What I would like to be able to use is an auto.master file and an auto.data file to do this and have the credentials provided via sssd. I was able to get this to work without sssd (i.e just autofs and a credential file already), But the server is going to be accessed by many users, so a credentials file isn't the way to go about it. Thanks, Thomas

Feature request: Partial id_mapping
by Joakim Tjernlund 25 Aug '16

25 Aug '16

Getting to the of our AD domain migration but there is one step I haven't solved. Our users has UID/GID in the new domain while the already present users in the new domain does not. Assigning UID/GID to all users does not sit well with upstream IT so I am looking at what to do with these when they visit/access our site. What comes to mind is partial id_mapping, if a user had UID/GID in the AD use that, otherwise do id_mapping for that user(preferably the same way samba does it since we already have a samba based interim solution). I haven't found a way to do that in sssd, is there? Maybe I am just full of it and this is really a bad idea?

DDNS update against Windows AD when switching to WiFi ?
by Joakim Tjernlund 24 Aug '16

24 Aug '16

Currently we have different IP addresses when using wired(Ethernet) and WiFi. I would like sssd to refresh its DDNS record whenever I switch between wired and WiFi, is this possible? So far I have only managed to refresh DDNS by restarting sssd but maybe there is a better way? Jocke

sssd seems seems not to respect default_realm = xxx ?
by Joakim Tjernlund 23 Aug '16

23 Aug '16

I changed the default REALM in krb5.conf but that did not have any effect on logins. I had to change the order of domains = in sssd.conf for logins to switch over to the new default domain. Should not sssd respect default_realm = xx in krb5.conf? Using sssd 1.13.4 Jocke

adcli --service-name strangeness
by Joakim Tjernlund 23 Aug '16

23 Aug '16

If I add --service-name="nfs" when joining a domain I do not get any host/* or RestrictedKrbHost/* entries in my keytab. Is this intentional? Jocke

adcli --service-name="host" vs. --user-principal=host/gentoo-lab.transmode.se@TRANSMODE.SE?
by Joakim Tjernlund 23 Aug '16

23 Aug '16

Is there a difference between the above two options? Also, I have always wondered why there is two version of ever service as in: host/GENTOO-LAB(a)TRANSMODE.SE vs. host/gentoo-lab.transmode.se(a)TRANSMODE.SE Jocke

DDNS not working due to non FQDN hostname
by Joakim Tjernlund 22 Aug '16

22 Aug '16

Discovered why DDNS was not working in this ticket: https://fedorahosted.org/sssd/ticket/2565 May I suggest that if gethostname() returns a non . name, sssd should automatically add the configured SSSD domain name in sssd.conf ( [domain/domain.name] ) Jocke

Announcing SSSD 1.14.1
by Jakub Hrozek 19 Aug '16

19 Aug '16

=== SSSD 1.14.1 === The SSSD team is proud to announce the release of version 1.14.1 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 == * The IPA provider now supports logins with enterprise principals (also known as additional UPN suffixes). This functionality also enabled Active Directory users from trusted AD domains who use an additional UPN suffix to log in. Please note that this feature requires a recent IPA server. * When a user name is overriden in an IPA domain, resolving a group these users are a member of now returns the overriden user names * Users can be looked up by and log in with their e-mail address as an identifier. In order to do so, an attribute that represents the user's e-mail address is fetched by default. This attribute can by customized by setting the ldap_user_email configuration option. * A new ad_enabled_domains option was added. This option lets the administrator select domains that SSSD should attempt to reach in the AD forest SSSD is joined to. This option is useful for deployments where not all domains are reachable on the network level, yet the administrator needs to access some trusted domains and therefore disabling the subdomains provider completely is not desirable. * The sssctl tool has two new commands active-server and servers that allow the administrator to observe the server that SSSD is bound to and the servers that SSSD autodiscovered * SSSD used to fail to start when an attribute name is present in both the default SSSD attribute map and the custom ldap_user_extra_attrs map * GPO policy procesing no longer fails if the gPCMachineExtensionNames attribute only contains whitespaces * Several commits fix regressions related to switching all user and group names to fully qualified format, such as running initgroups for a user who is only a member of a primary group * Several patches fix regressions caused by splitting the database into two ldb files, such as when user attributes change without increasing the modifyTimestamp attribute value * systemd unit files are now shipped for the sssd-secrets responder, allowing the responder to be socket-activated. To do so, administrators should enable the sssd-secrets.socket and sssd-secrets.service systemd units. * The sssd binary has a new switch --disable-netlink that lets sssd skip messages from the kernel's netlink interface. * A crash when entries with special characters such as '(' were requested was fixed * The ldap_rfc_2307_fallback_to_local_users option was broken in the previous version. This release fixes the functionality. == Packaging Changes == * The NFS ID-mapping plugin was moved to its own subpackage == Documentation Changes == * A new option ad_enabled_domains was added * A new LDAP attribute mapping for e-mail addresses called ldap_user_email was added == Tickets Fixed == https://fedorahosted.org/sssd/ticket/2789 Warn if ad_server contains IP address

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.

[root@node24 ~]# ifdown ib0 [root@node24 ~]# service sssd status sssd dead but pid file exists I have also noticed that sssd will not start on boot. 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. Can anyone explain this behavior and tell me what I might do to prevent it? -- ____ *Note: UMDNJ is now Rutgers-Biomedical and Health Sciences* || \\UTGERS |---------------------*O*--------------------- ||_// Biomedical | Ryan Novosielski - Senior Technologist || \\ and Health | novosirj(a)rutgers.edu - 973/972.0922 (2x0922) || \\ Sciences | OIRT/High Perf & Res Comp - MSB C630, Newark `'
