[PATCH] LDAP: Inform about small range size
by Lukas Slebodnik 09 Oct '15

09 Oct '15

ehlo, I was reprodicing other bug and it took me some time to find out why I was not able to resolve user. RID was bigger than range size. I saw just general message about id mapping failer [sdap_save_user] (0x0400): Processing user matthewbe [sdap_save_user] (0x1000): Mapping user [matthewbe] objectSID [S-1-5-21-2997650941-1802118864-3094776726-200065] to unix ID [sdap_idmap_sid_to_unix] (0x0080): Could not convert objectSID [S-1-5-21-2997650941-1802118864-3094776726-200065] to a UNIX ID ^^^^^^ Default range size is 200000 [sdap_save_user] (0x0020): Failed to save user [matthewbe] [sdap_save_users] (0x0040): Failed to store user 0. Ignoring. Feel free to propose better debug message. I think it would simplify debugging. LS

[PATCH] SUDO: Support the IPA schema
by Michal Šrubař 09 Oct '15

09 Oct '15

Hi guys, I spent some time working at this ticket https://fedorahosted.org/sssd/ticket/1108 and I think it's finally ready to be reviewed by others. Description of the problem and scope of the changes can be found in the commit message. I also wrote some unit tests but the patch is a quite long already so I think it would be better to send the tests as an another patch. Or should I create a patch for each modified file?

[PATCH] DYNDNS: Add a new option dyndns_server
by Jakub Hrozek 28 Jul '15

28 Jul '15

Hi, one of our users ran into an interesting problem -- her AD infrastructure was different from the DNS server. Because by default, we perform update against the server we're connected to, the DNS update didn't work. Per Simo's suggestion, I've implemented a new option that allows the administrator to override the DNS server used for DNS updates.

[PATCHES] AUDIT: Add audit support for SSSD
by Michal Židek 21 Jul '15

21 Jul '15

These two patches are initial patches for tickets https://fedorahosted.org/sssd/ticket/2373 https://fedorahosted.org/sssd/ticket/2372 I will add wrappers for more libaudit functions as needed in later patches. As for now, the audit support is not build by default so you need to run --with-libaudit. I would like to make it default when we have the above tickets solved. Thanks, Michal

[PATCH] Add integration tests
by Nikolai Kondrashov 28 Apr '15

28 Apr '15

Hi everyone, This is my attempt to add basic integration tests. There are almost no tests there at the moment and this is mostly about the infrastructure and the way we might do it. I will be glad to answer any questions and receive any comments or suggestions. I'm sure I did a lot of things in a wrong way :) Thank you!

Design discussion: Mapping user names of proxy users onto Kerberos principals
by Jakub Hrozek 22 Apr '15

22 Apr '15

Hi, we talked about implementing ticket #2509 with Pavel in person, but it would be nice to see if other other developers agree before all the code is written :-) The design page is here: https://fedorahosted.org/sssd/wiki/DesignDocs/KerberosPrincipalMappingToPro… For your convenience, the text of the design page is also copied below: = Mapping Proxy ID provider names to Kerberos principals = Related ticket(s): * https://fedorahosted.org/sssd/ticket/2509 === Problem statement === Some users are migrating to SSSD from a legacy configuration that consisted of a traditional UNIX user stored in `/etc/passwd` and managing their Kerberos tickets either with the use of some GUI tool or just command-line `kinit`. While these users can use SSSD by configuring the `id_provider` proxy, very often the name of their UNIX user is different from the name of their company-wide Kerberos credentials. This feature helps the above use-case by mapping their UNIX user name to the Kerberos principal name. === Use cases === Joe User has a company laptop where his UNIX user has been traditionally named `joe`. At the same time, his company Kerberos principal is called `juser(a)EXAMPLE.COM`. Joe would like to start using SSSD to leverage features like offline kinit without having to rename his UNIX user and chown all his local files to the corporate user ID. === Overview of the solution === The Kerberos provider will acquire a new option that describes how are the user names from the ID provider mapped onto the user part of the Kerberos principal. The user would then add the appropriate mapping to the `domain` section of `sssd.conf`. === Implementation details === A new option `krb5_map_user` would be added to the Kerberos auth code. This option would have form similar to how we map the LDAP extra attributes, that is `local_name:krb5_name`. When mapping exists for the user who is authenticating, the krb5_auth module would use that user name for calls like `find_or_guess_upn` instead of `pd->name`. We should consider whether to keep using `pd->name` or introduce another attribute to the `krb5_child_req` structure. === Configuration changes === A new configuration option tentatively called `krb5_map_user` would be added. This option is unset by default, which means whatever user name the ID provider stores will be used. === How To Test === 1. Prepare a Kerberos KDC, add a user principal (`juser(a)EXAMPLE.COM`) 1. Add a local user using `useradd` with name that differs from Kerberos principal in the name portion. (`joe`) 1. Configure SSSD with `id_provider=proxy` with `proxy_lib_name=files` and `auth_provider=krb5` pointing to our test KDC 1. Attempt to authenticate using a PAM service. The authentication should fail and the logs would show authentication as `joe(a)EXAMPLE.COM` 1. Set `krb5_map_user` to `joe:juser` and restart SSSD. 1. Authenticate again. This time, authentication should succeed and the user's klist output should list `juser(a)EXAMPLE.COM`. The `id(1)` output should still list `joe`, though. 1. Test that Kerberos ticket renewals still work 1. Test that delayed kinit still works. === Authors === * Jakub Hrozek <jhrozek(a)redhat.com>

[PATCH] sdap: properly handle binary objectGuid attribute
by Sumit Bose 25 Mar '15

25 Mar '15

Hi, this patch tries to resolve https://fedorahosted.org/sssd/ticket/2588 by properly handling binary objectGUID values. In general there shouldn't be an issue because this ID is not used for AD user. But if the binary value starts with 0x00 there might be issues saving the user object to the cache. bye, Sumit

[PATCH] RFC: Support both cmocka 1.0 and pre-1.0 API at the same time
by Jakub Hrozek 25 Mar '15

25 Mar '15

Hi, the attached two patches add a way to detect pre-1.0 cmocka and adds compatible definitions in the first patch and uses them to convert a single unit test. I found the approach ugly myself, so much that I'm considering converting all cmocka-based tests to cmocka-1.0 and don't compile the cmocka tests at all unless 1.0 or later is present on the system. It's not functionality after all, "just" tests and for CI we could add cmocka-1.0 to the CI system ourselves.. Opinions?
