There seems to be a bug to connect SECURE to an LDAP server.

The following script is working fine if I connect using the ldap:// protocol. However, connecting to the LDAP server through SSL (ldaps://) the bind fails with the error "DSA is unwilling to perform (Error 53)"

The LDAP server is configured for SSL.

function checkerror( $ldap, $stepinfo )
{
    if (ldap_errno($ldap) != 0) { 
        $ldaperr = ldap_errno( $ldap );
        $ldapmsg = ldap_error( $ldap );
        print "<br><b>ERROR at $stepinfo: $ldapmsg ($ldaperr)</b></br>\n";
        return FALSE;
    }
    return TRUE;
}
    
function doit( $ldap_server )
{
    $basedn      = "dc=mydc,o=myorg";
    $searcharg   = "sn=F*";
    $ldap_rdn    = "uid=myname,cn=users,dc=mydc,o=myorg";
    $ldap_passwd = "mypassword";

    print "Connecting to ldap server <B>$ldap_server</B> at port <B>$ldap_port</B><BR>\n";
    $ldap = ldap_connect( $ldap_server );

    if( checkerror( $ldap, "ldap_connect" ) == FALSE ) { return; }

    print "Binding to ldap server using rdn <B>$ldap_rdn</B><BR>\n";
    $bind = ldap_bind($ldap, $ldap_rdn, $ldap_passwd );
    
    if( checkerror( $ldap, "ldap_bind" ) == FALSE ) { return; }

    $mysuccess = ldap_search( $ldap, $basedn, $searcharg );

    if( checkerror( $ldap, "ldap_search" ) == FALSE ) { return; }

   $sr = $mysuccess;
   $ds = $ldap;

   echo "Number of entires returned is <B>".ldap_count_entries($ds,$sr)."</B><p>\n"; 

   $info = ldap_get_entries($ds, $sr); 
   echo "Data for ".$info["count"]." items returned:<p>"; 

   for ($i=0; $i<$info["count"]; $i++) { 
       echo "dn is: ". $info[$i]["dn"] ."<br>\n"; 
       echo "first cn entry is: ". $info[$i]["cn"][0] ."<br>\n"; 
       echo "first email entry is: ". $info[$i]["mail"][0] ."<p>\n"; 
   } 

    ldap_close($ldap);
    return TRUE;
}

doit( "ldap://myserver/" );
doit( "ldaps://myserver/" );
