IIRC libldap was linked against OpenSSL in CentOS/RHEL 5. In more recent 
versions it's linked against libnss because of Red Hat's 
PKCS#11-everywhere-plans. This is a significant change regarding TLS 

=> first try to get your ldaps://ldaptest.example.com working with ldapsearch 
command-line tool

Also note that libldap reads a system-wide LDAP client configuration file 
which might falsely set additional TLS related parameters. See ldap.conf(5) 
for details, especially env var LDAPNOINIT and sections TLS OPTIONS and FILES.

Ciao, Michael.
