Description Andrian Nord 2012-03-25 22:09:36 UTC
This is required for anyone who are using sys-auth/sssd for system auth and trying to launch 32bit application, which needs user authentication info.

Way to reproduce:
1. Install and configure sssd for external login storage use
2. emerge acroread
3. acroread

Results:
acroread doesn't start without any error particular error or action (no splash, nothing), with exception of
"(acroread:6960): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (5000)"

Workaround:
/etc/init.d/nscd start

but it conflicts with sssd caching capabilities.

In my opinion, a branch of 1.8 not vulnerable

Re-assigning to multilib@
Comment 3 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2014-05-27 13:06:23 UTC
What do we need in multilib here?

I would suspect at least the PAM and NSS modules. Likely also the libraries in /usr/lib64, and probably the krb5 plugin.

What about /usr/lib64/sssd? Is that used by the daemon or by the libraries?
Comment 4 Andrian Nord 2014-05-27 18:11:59 UTC
I don't see any use of this libraries by anything aside the daemon. They seems to be it's plugins for various techniques.

PAM, NSS and krb5 32bit plugins should do the trick, IMO.

BTW that's still an issue (I need to run nscd from time to time to work with 32bit apps, namely a lot of Steam games), if you wonder.
Comment 5 Lukas Slebodnik 2014-06-28 14:34:52 UTC
The only necessary files which should be multilib(32,64) are files which are packaged in sssd-client on fedora. http://koji.fedoraproject.org/koji/rpminfo?rpmID=5208096

Some of them will not be build on gentoo, because sssd is built without samba.

It should be these thee files.

Just got bitten by this problem too. Is there any progrees w.r.t multilib and sssd?

Thanks for the reminder. I will try to do it today, though it seems to have grown in new dependencies ;/.

Very much appriciated, thank you.

I guess this was not an easy task :)
Seems like you have to rebuild the whole stack just to get to the
client libs.
sssd really needs separate server and client build targets

It is not. The whole thing would be much better as separate packages. I'm still trying to find out how much of configure we need to stub.

Hate to be a pest, but has there been any progress?
Comment 13 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2014-10-28 07:28:04 UTC
Not really. Need a patch, and a good one.
Comment 14 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2014-11-20 17:57:54 UTC
Good news, everyone!

$ qlist sssd | grep lib32
/lib32/security/pam_sss.so
/lib32/libnss_sss.so.2.0.0
/usr/lib32/krb5/plugins/libkrb5/sssd_krb5_locator_plugin.so
/lib32/libnss_sss.so.2
/lib32/libnss_sss.so

Now I just have to test it in a dedicated chroot to make sure it doesn't depend on some unnecessary multilib libraries being installed.

Nice!

It will be interesting to see what magic you had to do for this :)

+*sssd-1.12.2-r1 (20 Nov 2014)
+
+  20 Nov 2014; Michał Górny <mgorny@gentoo.org> +sssd-1.12.2-r1.ebuild:

Hopefully it builds fine with minimal set of dependencies necessary.
