Hi Rex, Looking closer at the logging which you provided when debug_level = 4, the important part is:
[sss_ldap_init_sys_connect_done] (0x0020): ldap_install_tls failed: [Connect error] [(unknown error code)] This looks very similar to this upstream bug report: https://github.com/SSSD/sssd/issues/5531 In which case, I believe the below commit should fix the issue: commit da55e3e69707de416b7949d08c165c950090bbb6 From: Iker Pedrosa <ipedr...@redhat.com> Date: Wed, 3 Mar 2021 15:34:49 +0100 Subject: ldap: retry ldap_install_tls() when watchdog interruption Link: https://github.com/SSSD/sssd/commit/da55e3e69707de416b7949d08c165c950090bbb6 I will make some test packages for Bionic, Focal, Hirsute and Impish. Will you be able to try some test packages? I will also try and reproduce myself, but this looks like a unreliable race condition between the watchdog and ldap_install_tls().
