I think the best way forward here is to get a core dump, so we can have a better idea of where the crash is happening.
I induced a crash in my test sssd container, and since I have apport installed, a crash file was produced in /var/crash: # ll /var/crash/ total 644 drwxrwxrwt 2 root root 4 Nov 1 20:34 ./ drwxr-xr-x 13 root root 15 Sep 19 19:18 ../ -rwxr-xr-x 1 root root 0 Nov 1 20:34 .lock* -rw-r----- 1 root root 593417 Nov 1 20:34 _usr_lib_x86_64-linux-gnu_sssd_sssd_be.0.crash Could you please check if you have a recent crash file related to sssd in that directory. If not, do this: sudo apt install apport # check the kernel core_pattern: # sysctl kernel.core_pattern kernel.core_pattern = |/usr/share/apport/apport %p %s %c %P And then restart sssd and induce the crash again, and then hopefully you will have a crash file and we can go from there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1684295 Title: sssd fails with 'Exiting the SSSD.
