Hi,
I have PERL code for LDAP that take userid and password...and authenticate the user. Now I want to make the C++ code for the same. How can I make that?
Perl code:
#!usr/local/bin/perl      
use  Net::LDAP;
use Term::ReadKey;

$user= "";
$password= "";



print " Enter Username: ";
$user =<STDIN>;
chop($user);

print " Enter Password: ";
ReadMode('noecho');
$password = <STDIN>;
chop($password);
ReadMode('normal');


$LDAP_HOST            = 'ids.gm.com';
$LDAP_PORT            = 389;
$LDAP_BASE_DN             = 'ou=people,ou=intranet,dc=gm,dc=com';
$LDAP_USER_ATTRIBUTE      = 'gmguid';
$TRUE = 1;

# See if the Password is NULL
if(length($password)==0)
      {
      print "\nPassword field is left EMPTY.\n";
      }

#Establish a connection to the LDAP Server
my $ldap = new Net::LDAP($LDAP_HOST, port=>$LDAP_PORT, onerror=>'undef');
if(!$ldap)
      {
      # If the Connection is unsuccessful      
      print "\nConnection to LDAP Server is UNSUCCESFUL.\n";    
      }

#Validate the User ID and Get its Distinguished Name
my $dn = $LDAP_USER_ATTRIBUTE . '=' . $user . ',' . $LDAP_BASE_DN;
if(!$dn)
      {    
      # No Entry exists that matches $USERDN      
      print "\nInvalid USERID.\n";    
      }  

#Authenticate the User       
if (defined($ldap->bind($dn, password=>$password)))
      {
      print "\nUSER is AUTHINTICATED.\n";
      }
else
      {
      print "\nInvalid PASSWORD.\n";
      }
$ldap->unbind();

OpenLDAP (http://www.openldap.org/) is a library that you'll need and find helpful for doing LDAP in C/C++. For the above, see http://www.openldap.org/devel/cvsweb.cgi/~checkout~/tests/progs/slapd-bind.c?rev=1.24&hideattic=1&sortbydate=0

The relevant part is

static int
do_bind( char *uri, char *dn, struct berval *pass, int maxloop,
      int force, int chaserefs, int noinit, LDAP **ldp )
{
      LDAP      *ld = ldp ? *ldp : NULL;
      int        i, rc = -1;
      pid_t      pid = getpid();

      if ( maxloop > 1 )
            fprintf( stderr, "PID=%ld - Bind(%d): dn=\"%s\".\n",
                   (long) pid, maxloop, dn );

      for ( i = 0; i < maxloop; i++ ) {
            if ( !noinit || ld == NULL ) {
                  int version = LDAP_VERSION3;
                  ldap_initialize( &ld, uri );
                  if ( ld == NULL ) {
                        tester_perror( "ldap_initialize", NULL );
                        rc = -1;
                        break;
                  }

                  (void) ldap_set_option( ld, LDAP_OPT_PROTOCOL_VERSION,
                        &version );
                  (void) ldap_set_option( ld, LDAP_OPT_REFERRALS,
                        chaserefs ? LDAP_OPT_ON: LDAP_OPT_OFF );
            }

            rc = ldap_sasl_bind_s( ld, dn, LDAP_SASL_SIMPLE, pass, NULL, NULL, NULL );
            if ( rc ) {
                  unsigned first = tester_ignore_err( rc );

                  /* if ignore.. */
                  if ( first ) {
                        /* only log if first occurrence */
                        if ( force < 2 || first == 1 ) {
                              tester_ldap_error( ld, "ldap_sasl_bind_s", NULL );
                        }
                        rc = LDAP_SUCCESS;

                  } else {
                        tester_ldap_error( ld, "ldap_sasl_bind_s", NULL );
                  }
            }
                  
            if ( !noinit ) {
                  ldap_unbind_ext( ld, NULL, NULL );
                  ld = NULL;
            }

            if ( rc != LDAP_SUCCESS ) {
                  break;
            }
      }

      if ( maxloop > 1 ) {
            fprintf( stderr, " PID=%ld - Bind done (%d).\n", (long) pid, rc );
      }

      if ( ldp && noinit ) {
            *ldp = ld;

      } else if ( ld != NULL ) {
            ldap_unbind_ext( ld, NULL, NULL );
      }

      return rc;
}
