Hello all, I have written a sample code to connect to LDAP server via SSL running on port 10389(ldap) & 10636(ldaps). But the sample application fails to set the options for the SSL connection. 

I do not want to verify the certificate correctness at this moment. Can someone help fix this sample code?? 

#include <stdio.h>

#define LDAP_DEPRECATED 1

#include <ldap.h>

 

#define BIND_DN "dc=example,dc=com"

#define BIND_PW "secret"

 

int main() {

LDAP *ld;

int rc;

int reqcert = LDAP_OPT_X_TLS_NEVER;

int version = LDAP_VERSION3;

int ret(0);

 

if (ldap_initialize (&ld, "ldap://192.168.1.51:10389")) {

        perror("ldap_init"); /* no error here */

        return(1);

    }

    rc  = ldap_set_option (ld, LDAP_OPT_PROTOCOL_VERSION, &version);

if(rc != LDAP_OPT_SUCCESS){

printf("Setting LDAP_OPT_PROTOCOL_VERSION failed: %s\n",ldap_err2string(rc));

}

 

    rc = ldap_set_option (ld, LDAP_OPT_X_TLS_REQUIRE_CERT, &reqcert);

if(rc != LDAP_OPT_SUCCESS){

printf("Setting LDAP_OPT_X_TLS_REQUIRE_CERT failed: %s\n",ldap_err2string(rc));

}

   

    rc = ldap_start_tls_s(ld, NULL, NULL);

    if (rc != LDAP_SUCCESS) {

        printf("ldap_start_tls failed: %s\n",ldap_err2string(rc));

    }

   

    rc = ldap_bind_s(ld, BIND_DN, BIND_PW, LDAP_AUTH_SIMPLE);

   

    if( rc != LDAP_SUCCESS )

    {

        fprintf(stderr, "ldap_simple_bind_s: %s\n", ldap_err2string(rc) );

        return( 1 );

    }

    ldap_unbind(ld);

}

The program always fails with:

The server does support ldaps and ldap+tls. Can some one please help??
