Disabling SSSD Discovery Service
by eric.aiken＠capitalstream.com 13 Jan '16

13 Jan '16

I’ve been beating my head over this. After upgrading RHEL5 systems to RHEL6, the kerberos/ldap services quit working correctly. I’ve resolved most of the issues. I also embraced SSSD. My remaining challenge is to disable the SSSD Discovery service. Authentication and authorization works, it’s just DNS round-robins DC’s that are not reachable and this ultimately causes failures (and latency) In short I need to hard code who the client talks to. Inevitably I keep finding the client doing a DNS lookup for domaindnszones.<domain>. Due to limitations in MS windows DNS, This returns IP’s for DC’s in VLANs not accessible to certain subnets. Round-Robin DNS with subnet masking doesn’t work for clients that are not AD CSE capable. (eg AD client side extension). Even if I could get the net masking to work, I don’t believe it would work for our IP space as the necessary netmask would need to be a class A , thereby getting all the DC’s again. For the record AD (and our IP subnets) are configured properly for sites and services. I’ve tried lots of variations and configurations of: hardcoding: kdc = admin_server = krb5_backup-server = dns_lookup_realm = false dns_lookup_dc = false ldap_uri ldap_backup_uri I tried working with sssd-ad as it allows you to define ad_server and ad_enable_dns_sites. Again the sssd discovery service continues to try and “control” where to look. From my research I’m not alone, there are others with similar challenges, but I’ve yet to find someone with an “old-school” configuration. Is there a way to tell sssd use “ these and only these” DC’s for Kerberos and LDAP on a client? I’ll manage HA and load balancing. Thanks for your thought and advise.

Is the new IETF schema proposal DBIS (a replacement for NIS and RFC2307) something SSSD will support in the long term? Seems like there are some advantages.... Best regards, PieterB

Re: Potentially false errors when changing user password via `passwd` using krb5 as the chpass_provider
by Jesse Szwedko 12 Jan '16

12 Jan '16

Hi Jakub! Thank you for the additional information, what you said seems to fit (that the change operation works, but not kinit with the new password). They should be talking to the same server, but I'll double check. I'll check into this on Monday and write back. -Jesse

Potentially false errors when changing user password via `passwd` using krb5 as the chpass_provider
by Jesse Szwedko 08 Jan '16

08 Jan '16

Hi all, We are seeing some strange behavior when using passwd (via sssd using the krb5 password provider) to change a user's password where the command reports that the change fails due to "Authentication token manipulation error" every other time (meaning, it will error, then not error, then error, then not error, and so forth, in sequence). However, the operation is actually successful (in that it changes the password) even when it reports the error. We saw this behavior with sssd versions 1.12.2 and 1.13.3 (we tried upgrading to see if maybe the issue had been addressed). Shell output executing passwd: [test-user@ip-172-31-44-254 ~]$ passwd Changing password for user test-user. Current Password: New password: Retype new password: passwd: all authentication tokens updated successfully. [test-user@ip-172-31-44-254 ~]$ passwd Changing password for user test-user. Current Password: New password: Retype new password: passwd: Authentication token manipulation error Our sssd.conf: http://ix.io/neC SSSD logs: http://ix.io/neq The logs show the use of `passwd` twice, where the first time did not report the error, and the second did. You'll note that when `passwd` reported the error, that sssd logged "9027 (Wed Jan 6 21:08:57 2016) [[sssd[krb5_child[31229]]]] [sss_child_krb5_trace_cb] (0x4000): [31229] 1452114537.218562: Received error from KDC: -1765328360/Preauthentication failed". Using `kpasswd` directly does not exhibit this behavior, i.e. it changes the password and reports success in all instances where we've tried it. The KDC we are authenticating against is managed service from Amazon Web services, Simple AD, which feels like it is Samba (somewhat corroborated by this answer on ServerFault: http://serverfault.com/questions/746194/is-it-possible-to-use-kerberos-over… which states "In addition, Amazon's Simple AD is Samba AD built with Heimdal kerberos"). We do not have a lot of insight into the configuration of the server, but can query it via LDAP and kerberos methods if any additional information would be useful. This isn't a blocking issue for us since the password change is actually successful, but it is somewhat of a curiosity and loose end I was hoping someone could assist with. Thank you! -Jesse

Does simple access provider work with netgroup ?
by aaron wang 08 Jan '16

Hi All, Simple access provider works well with posixGroup on the LDAP, but does it work with netgroup as well ? If yes, how to specify a netgroup in the simple_allow_group list ? Thanks, Aaron

Ticket expiring problems still
by Thackeray, Neil L 05 Jan '16

05 Jan '16

I am having a frustrating time trying to figure out what is going on with these Ubuntu servers. I have tried to use msktutil as some have suggested, but this hasn't worked for me. Every 7 days on the mark I lose my domain connection and have to run realm leave/realm join again. I ran msktutil the day before the ticket was about to expire, so it should have worked. This is only a problem on Ubuntu, CentOS works perfectly fine. I even have one Ubuntu server that works. I also have the problem that the sssd init script, wherever that is now, sometimes thinks that sssd is still running and won't start again. I then have to run 'sssd -D' if I don't want to restart the server. This is what I get running msktutil. msktutil --auto-update --verbose: -- init_password: Wiping the computer password structure -- generate_new_password: Generating a new, random password for the computer account -- generate_new_password: Characters read from /dev/udandom = 86 -- get_dc_host: Attempting to find a Domain Controller to use (DNS SRV RR TCP) -- get_dc_host: Found DC: udc05.ad.mydomain.com -- get_dc_host: Canonicalizing DC through forward/reverse lookup... -- get_dc_host: Found Domain Controller: udc05.ad.mydomain.com -- get_default_keytab: Obtaining the default keytab name: FILE:/etc/krb5.keytab -- create_fake_krb5_conf: Created a fake krb5.conf file: /tmp/.msktkrb5.conf-TSzpEQ -- reload: Reloading Kerberos Context -- get_short_hostname: Determined short hostname: myserver-domain-foo-com Error: The SAM name (myserver-domain-foo-com$) for this host is longer than the maximum of MAX_SAM_ACCOUNT_LEN characters You can specify a shorter name using --computer-name -- ~KRB5Context: Destroying Kerberos Context This appears to have worked, but it didn't. msktutil --update --computer-name MYSERVER --verbose: -- init_password: Wiping the computer password structure -- generate_new_password: Generating a new, random password for the computer account -- generate_new_password: Characters read from /dev/udandom = 82 -- get_dc_host: Attempting to find a Domain Controller to use (DNS SRV RR TCP) -- get_dc_host: Found DC: udc05.ad.mydomain.com -- get_dc_host: Canonicalizing DC through forward/reverse lookup... -- get_dc_host: Found Domain Controller: udc05.ad.mydomain.com -- get_default_keytab: Obtaining the default keytab name: FILE:/etc/krb5.keytab -- create_fake_krb5_conf: Created a fake krb5.conf file: /tmp/.msktkrb5.conf-ozv4A6 -- reload: Reloading Kerberos Context -- finalize_exec: SAM Account Name is: MYSERVER$ -- try_machine_keytab_princ: Trying to authenticate for MYSERVER$ from local keytab... -- switch_default_ccache: Using the local credential cache: FILE:/tmp/.mskt_krb5_ccache-ewj6uW -- finalize_exec: Authenticated using method 1 -- ldap_connect: Connecting to LDAP server: udc05.ad.mydomain.com try_tls=YES -- ldap_connect: Connecting to LDAP server: udc05.ad.mydomain.com try_tls=NO SASL/GSSAPI authentication started SASL username: MYSERVER$(a)AD.MYDOMAIN.COM SASL SSF: 56 SASL data security layer installed. -- ldap_connect: LDAP_OPT_X_SASL_SSF=56 This is what I think is the pertinent portions of the logs from when the computer cant connect anymore. sssd_ad.mydomain.com.log: (Wed Nov 4 15:26:09 2015) [sssd[be[ad.mydomain.com]]] [sdap_get_tgt_recv] (0x0400): Child responded: 14 [Preauthentication failed], expired on [0] (Wed Nov 4 15:26:09 2015) [sssd[be[ad.mydomain.com]]] [sdap_kinit_done] (0x0100): Could not get TGT: 14 [Bad address] (Wed Nov 4 15:26:09 2015) [sssd[be[ad.mydomain.com]]] [sdap_cli_kinit_done] (0x0400): Cannot get a TGT: ret [1432158219](Authentication Failed) (Wed Nov 4 15:26:09 2015) [sssd[be[ad.mydomain.com]]] [fo_set_port_status] (0x0100): Marking port 389 of server 'udc02.ad.mydomain.com' as 'not working' (Wed Nov 4 15:26:09 2015) [sssd[be[ad.mydomain.com]]] [ad_user_data_cmp] (0x1000): Comparing LDAP with LDAP (Wed Nov 4 15:26:09 2015) [sssd[be[ad.mydomain.com]]] [fo_set_port_status] (0x0400): Marking port 389 of duplicate server 'udc02.ad.mydomain.com' as 'not working' syslog: Nov 4 15:26:09 myserver [sssd[ldap_child[25833]]]: Failed to initialize credentials using keytab [MEMORY:/etc/krb5.keytab]: Preauthentication failed.

Announcing SSSD 1.13.1
by Jakub Hrozek 05 Jan '16

05 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 ==

ad provider - mangle user names
by Frank Ritchie 04 Jan '16

Hi all, Looking to have my cake and eat it too. I have alot of users that have been using Winbind for years. They currently log in with the workgroup, ie: WORKGROUP+username I would like to roll out SSSD with the ad provider. I would ideally like for a user to be able to log in as: WORKGROUP+username or username and sssd would know this is the same AD user. Is this possible? thx

SSSD offline authentication cache timtout question
by aaron wang 04 Jan '16

Hi All, 1. I plan to enable cache_credential flag in the system, and it looks like that "account_cache_expiration", "offline_credentials_expiration", "offline_failed_login_attempts". These three options needs to be set as well, as their default value is unlimited, which may bring some security concerns. Is there any other options I need to take care if I want to enable offline authentication ? 2. Also, I have some doubt about the difference between "account_cache_expiration" and "offline_credentials_expiration". I know "account_cache_expiration" is per domain, but "offline_credentials_expiration" is for PAM responder. E.g. I set account_cache_expiration to 10 days, offline_credentials_expiration to 2 days. What's the use case of the cache after day 2 ? 3. Both "offline_credentials_expiration" and "account_cache_expiration" are counted after last successful login. Does the successful login after LDAP offline count ? Will the successful login after LDAP offline extend the life of the cache ? Thanks for any information. Thanks, Aaron
