What can I do to troubleshoot this? OpenLDAP client says

to the same server, and I'm using the same ldap.conf, nsswitch.conf, and
Apart from seeing configurations and command lines, I have found the
full output of the openssl client to be useful for diagnosing my own
echo | openssl s_client -debug -showcerts -connect SERVER:636 2>&1 |
The openssl client connects to the server and negotiates SSL. Along
the way it verifies the certificate path. If it encounters an error,
it usually gives a useful error message.
Just use -d1 on ldapsearch and you'll get the OpenSSL diagnostic messages.
