To me it looks like a problem with your certificates. Try to verify them using openssl,
openssl verify -CApath /etc/ssl/certs -verbose /etc/ssl/servercerts/slapd.pem
% grep -R Certificate *.ldif
% directory2:/etc/ldap# openssl verify -CApath /etc/ssl/certs -verbose
So, the openssl command line can find the certificate chain. Why can't
