hi - using OpenLDAP 2.6.3 and finding that newer LDAP client libraries (like the one that comes with Ubuntu 22.04.1 LTS) can't complete a connection to the LDAP server's TLS port. A machine I have running Rocky 8.6, however, with OpenSSL 1.1.1k, connects just fine. This is using self-generated certificates, but the correct CA cert and server cert have been provided to SSSD to use for login. The two machines are using identical certificates and SSSD configuration files.
How do we begin to troubleshoot this? The trouble is seen in the SSSD log: (2023-01-09 21:08:26): [be[default]] [fo_resolve_service_send] (0x0100): [RID#13] Trying to resolve service 'LDAP' (2023-01-09 21:08:26): [be[default]] [get_server_status] (0x1000): [RID#13] Status of server '10.8.8.60' is 'name not resolved' (2023-01-09 21:08:26): [be[default]] [get_port_status] (0x1000): [RID#13] Port status of port 636 for server '10.8.8.60' is 'neutral' (2023-01-09 21:08:26): [be[default]] [fo_resolve_service_activate_timeout] (0x2000): [RID#13] Resolve timeout [dns_resolver_timeout] set to 6 seconds (2023-01-09 21:08:26): [be[default]] [get_server_status] (0x1000): [RID#13] Status of server '10.8.8.60' is 'name not resolved' (2023-01-09 21:08:26): [be[default]] [set_server_common_status] (0x0100): [RID#13] Marking server '10.8.8.60' as 'resolving name' (2023-01-09 21:08:26): [be[default]] [check_if_online_delayed] (0x2000): [RID#12] Check online req created.
