Description of problem:
a customer was complaining about sss_cache returning 2, ENOENT ( no entries
invalidated in the cache ).
Or even think about the possibility of always returning 0 since "no entries
invalidated" is also successful.
German said he reproduced this easily:
Well, I have reproduced very easily like this:
=======================
[root@ipatrust ~]# rm -rf /var/lib/sss/db/* 
[root@ipatrust ~]# systemctl restart sssd.service
[root@ipatrust ~]# sss_cache -G
No cache object matched the specified search
[root@ipatrust ~]# echo $?
2
[root@ipatrust ~]# sss_cache -U
No cache object matched the specified search
[root@ipatrust ~]# echo $?
2
This seems to be expected return "no entries" when there's nothing to invalidate.
Now:
[root@ipatrust ~]# id gparente
uid=142600006(gparente) gid=142600006(gparente) groups=142600006(gparente),142600015(newgroup)
[root@ipatrust ~]# sss_cache -U
[root@ipatrust ~]# echo $?
0
