Right, because ldap_start_tls_s() performs the LDAP start TLS operation,
but for ldaps the client is supposed to simply negotiate TLS/SSL upon
connection, without sending an LDAP operation first.
The Right Thing is to stop using ldap_init() and instead use
ldap_initialize(), passing it an URI of "ldaps://hostname".

Can you tell me which certificate should i use in the code.
The client only needs the CA certificate. Set the
LDAP_OPT_X_TLS_CACERTFILE option to the path to the PEM file, or set the

hashed paths. (Check out the docs for SSL_CTX_load_verify_locations() for
the details of the hashing.)
Note that in versions before 2.4.0, those are *global* options:
ldap_set_option() *must* be passed a NULL LDAP handle when setting them.
As of 2.4.0 they're per-LDAP-handle only and must be set on each handle
