As it's not currently possible for Wren-cli to access OpenLDAP directly, we embed a Wren script in a C application to complete this task.
<lang ecmascript>/* active_directory_connect.wren */
foreign class LDAP {
construct init(host, port) {}
foreign simpleBindS(name, password)
foreign unbind()
}
class C {
foreign static getInput(maxSize)
}
var name = ""
while (name == "") {
System.write("Enter name : ")
name = C.getInput(40)
}
var password = ""
while (password == "") {
System.write("Enter password : ")
password = C.getInput(40)
}
var ld = LDAP.new("ldap.somewhere.com", 389)
ld.simpleBindS(ld, name, password)
// do something here
ld.unbind()</lang>
<br>
We now embed this in the following C program, compile and run it.
<lang c>#include <stdio.h>
#include <stdio_ext.h>
#include <stdlib.h>
#include <string.h>
#include <ldap.h>
#include "wren.h"
