Hello, The /var/lib/sss/pubconf/known_hosts file is empty on a new installed FreeIPA server. I’ve already joined a machine to the domain but the file is still empty.
I can’t get it populated, already rebooted and/or restarted sssd without success. Looking on the web I came across this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1574778 It is Fedora related, but it’s the same version that I’m running, since I’m on CentOS 7.6. How can I check if is in fact this bug? Here are some errors on sssd_ssh with debug_level = 9 enabled: ==> /var/log/sssd/sssd_ssh.log <== (Tue Oct 8 21:10:37 2019) [sssd[ssh]] [sbus_remove_timeout] (0x2000): 0x55b758c55dc0 (Tue Oct 8 21:10:37 2019) [sssd[ssh]] [sbus_dispatch] (0x4000): dbus conn: 0x55b758c56e10 (Tue Oct 8 21:10:37 2019) [sssd[ssh]] [sbus_dispatch] (0x4000): Dispatching.
