Description: The client must call ldapssl_enable_clientauth before the first operation. This means before ldap_start_tls_s in the case of startTLS. However, the certname and keypassword (if any) are stored in the connection context. ldapssl_enable_clientauth will now allocate and store this connection context if it doesn't already exist, then set the certname and keypassword.
