ldap_start_tls_s() error NOT SUPPORTTED

["Reguera Gilarranz, Teresa" <teresa.regueragilarranz@es.unisys.com>]

Hello,

I'm trying to modify a C++ program that currently does an ldap_search() to do this search using a secure connection. Looking at some examples I saw I had to add the ldap_start_tls_s() function after the ldap_init(). I also noticed I had to set protocol version what I did...so I don't know why I'm getting the NOT SUPPORTED error...
If I tried with the ldapsearch from command line with -ZZ options, it works fine. Can anyone please give me any suggestion???

This is the code:


            pLDAP = ldap_init( hostname, 389  );
	if ( pLDAP == NULL ) {		
		return (Error)LDAPSSL_INIT_FAILED;
	} 

	static Uint32 version = LDAP_VERSION3;
	rc = ldap_set_option (pLDAP, LDAP_OPT_PROTOCOL_VERSION, (void*)&version);
              //that worked fine
	rc = ldap_start_tls_s(pLDAP, NULL, NULL);
              //that failed with NOT_SUPPORTED error
       	if (rc!= LDAP_SUCCESS) {		
		return LDAP_START_TLS_FAILED;
	} 

I have installed OpenLDAP 2.2.23 and OpenSSL 0.9.7e
Thanks a lot!!
