[SSSD] [PATCH] Unit tests for pam_sss using pam_wrapper (need help with CI..)

[Jakub Hrozek]

Hi,

the attached patches implement unit tests for the pam_sss module using
pam_wrapper and libpamtest. In my testing, the coverage is around 75%
with mostly the parts that require running as root being untested.

I worked on this patchset even though the features for 1.14 are in full
swing because there are several tickets that will require us to patch
pam_sss, so it's important to have the code that changes tested. In
addition, when we merge Dan's patches to use TLS with integration tests,
then we'll be able to also test authentication in integration tests
easily using libpamtest-python.

However, our CI fails for me constantly:

The strange thing is that running CI locally works fine and so does make
check. Can anyone help point me in the right direction as to what should
I check next? I suspect some of the environment variables might not be
set correctly, but I don't see why..
