(difficult to confirm without coredump/backtraces).
Would a stack trace of automount or the sssd daemon be sufficient?
No, I meant backtrace from a coredump. Maybe `ltrace` can help also, but I doubt `strace` is handy here.
I tried to compile the trivial reproducer from the GitHub Issue you linked to, but I'm getting an error when I try to compile it:
# gcc sssd_tester.c -o sssd_tester -lsss_nss_idmap -lpthread -ldl
sssd_tester.c: In function ‘thread’:
sssd_tester.c:12:5: warning: implicit declaration of function ‘sss_getpwnam’; did you mean ‘getpwnam’? [-Wimplicit-function-declaration]

| getpwnam
It looks like sss_getpwnam isn't defined in any of the header files in /usr/include, or I just can't find what package provides it.
Link against `/lib64/libnss_sss.so.2`:
```$ nm -D /lib64/libnss_sss.so.2 | grep sss_getpwnam
0000000000005f10 T _nss_sss_getpwnam_r@@EXPORTED```(no need to link against `sss_nss_idmap`)But why? It won't help to assure you face the same issue.
