Bug 525352 – sys-auth/sssd-1.12.1 - [load_backend_module] (0x0010): Unable to load ad module with path (/usr/lib64/sssd/libsss_ad.so), error: /usr/lib64/sssd/libsss_ad.so: cannot open shared object file: No such file or directory

[Description KK 2014-10-14 00:34:52 UTC]

I am using gentoo hardened-sources and today emerged sssd-1.12.1 with an aim to use it to get data from Samba 4 AD. According to the Samba wiki at https://wiki.samba.org/index.php/Local_user_management_and_authentication/sssd sssd from version 1.10.0 onwards should support the "AD id_provider".

Following their recommendations and using the suggested configuration file however results in sssd not being able to start with the following messages:
 * Starting sssd ...
 * start-stop-daemon: failed to start `/usr/sbin/sssd'                  [ !! ]
 * ERROR: sssd failed to start

Adding the debug and interactive option with logging to stederr when starting sssd reveals that it fails to open a required library file for the requested backend provider:
=====
[load_backend_module] (0x0010): Unable to load ad module with path (/usr/lib64/sssd/libsss_ad.so), error: /usr/lib64/sssd/libsss_ad.so: cannot open shared object file: No such file or directory
[be_process_init] (0x0010): fatal error initializing data providers
[main] (0x0010): Could not initialize backend [79]
Child [samba.example.com] exited with code [3]
=====

It turns out that required file /usr/lib64/sssd/libsss_ad.so is not being installed (for a complete list of files for the sssd package see https://www.archlinux.org/packages/community/x86_64/sssd/files/) - and that's regardless of the USE flag settings (tested with all flags except augeas, selinux, test): This file is not compiled and subsequently also nor being installed.

I assume the relevant path in the source tree for the backend provider should be sssd-1.12.1/src/providers/ad which after "ebuild sssd-ebuild-file compile" does not contain any binary objects.

reproducable: always
expected behaviour: the required libs for AD id provider should be installed

Ideally this should be covered by a special AD use flag if this is not too much of a hassle.

Thanks KK

Hi

Probably because samba4 is forced-disabled in the ebuild. Samba4 is still masked on Gentoo. Seehttps://bugs.gentoo.org/show_bug.cgi?id=489762
