TESTS: add a helper module with shared NSS constants Every module that reads the sssd_nss module directly copied around the same definition of NSS constants. This commit moves them into a single file to avoid code duplication. Reviewed-by: Pavel Březina <pbrezina@redhat.com> Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>

intg: Use bytes as input in ctypes Python module ctypes directly uses C functions and C functions expect "char *" as a string and not pointer to wide characters "wchar *". Reviewed-by: Martin Basti <mbasti@redhat.com>

sssd_id.py: Primary group should be returned for initgroups Side effect of this change was that some primary groups could not be resolved and therefore get_user_groups failed in override tests. We should do the same as "id user". return decimal representation GID if it cannot be mapped to name. Reviewed-by: Jakub Hrozek <jhrozek@redhat.com>

intg: Make location of sssd nss module configurable The path to sssd nss module (libsss_nss.so) was relative to prefix and expected subdirectory "lib". 32bit and 64bit platforms and different distributions use different paths. This patch allows to use python module sssd_id even with real module and not just integration tests. It is just required to prepare "config.py" with right path. e.g. cd ~/sssd/src/tests/intg [~/sssd/src/tests/intg]$ echo "NSS_MODULE_DIR = '/usr/lib64'" > config.py [~/sssd/src/tests/intg]$ python Python 2.7.12 (default, Jul 18 2016, 09:57:01) [GCC 6.1.1 20160621 (Red Hat 6.1.1-3)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sssd_id >>> sssd_id.get_user_gids('user') (1, 0, [5977, 1070, 5845, 1076, 1074, 10327, 5975, 5766]) Reviewed-by: Petr Čech <pcech@redhat.com>
