下面是我的用户修改自己密码的代码。这种形式完美无缺。现在这里的问题是我希望用户能够更改他们的电子邮件、电话,甚至他们的名字。我使用管理员帐户,因此它有权在 LDAP 中搜索每个人并检索有关每个人的所有信息。现在的问题是我不希望用户插入重复项,因此如果 LDAP 中已经存在电子邮件 bobizumi@stackoverflow.com 的人,则不应允许用户输入此电子邮件。姓名和电子邮件也是如此。我不确定如何搜索重复项,我假设它使用 ldap_search 和 ldap_get_entries 但我是使用 LDAP 编程的新手,所以我需要一些编程帮助来解决这个问题。如果我可以看到一个示例或有人可以向我展示一个示例,该示例可能可以防止名称重复和使用管理员权限进行 ldap 搜索,那么我可以从那里继续并自己完成其余的工作,但我真的只是坚持代码部分而不是逻辑。我找不到太多关于 ldap 文档及其与 PHP 或任何代码片段的集成和功能的示例,所以我一直在尝试 PHP 手册中的内容。

PHP:

function changePassword($server,$dn,$user,$oldPassword,$newPassword,$newPasswordCnf){
  global $message;

  error_reporting(0);

  $con=ldap_connect($server);
  ldap_set_option($con, LDAP_OPT_PROTOCOL_VERSION, 3);

  $findWhat = array ("cn","mail","*");
  $findWhere = $dn;
  $findFilter = "(uid=$user)";

  #bind anon and find user by uid
  $sr = ldap_search($con,$dn,$findFilter,$findWhat);
  $records = ldap_get_entries($con, $sr);
  // echo "<pre>";print_r($records);
  /* error if found more than one user */
  if ($records["count"] != "1") {
    $message[] = "Error E100 - Wrong user.";
    return false; 
  }else {
    $message[] = "Found user <b>".$records[0]["cn"][0]."</b>";
  }

  /* try to bind as that user */
  if (ldap_bind($con, $records[0]["dn"], $oldPassword) === false) {
    $message[] = "Error E104 - Current password is wrong.";
    return false;
  }
  else {    echo"TEST";
  $sr = ldap_search($con,$dn,$findFilter,$findWhat);
  $records = ldap_get_entries($con, $sr);
   echo "<pre>";print_r($records);
   }

  if ($newPassword != $newPasswordCnf ) {
    $message[] = "Error E101 - New passwords do not match! ";
    return false;
  }
  if (strlen($newPassword) < 8 ) {
    $message[] = "Error E102 - Your new password is too short! ";
    return false;
  }
  if (!preg_match("/[0-9]/",$newPassword)) {
    $message[] = "Error E103 - Your password must contain at least one digit. ";
    return false;
  }
  if (!preg_match("/[a-zA-Z]/",$newPassword)) {
    $message[] = "Error E103 - Your password must contain at least one letter. ";
    return false;
  }






  $entry = array();
  $entry["userPassword"] = "{SHA}" . base64_encode( pack( "H*", sha1( $newPassword ) ) );
  if (ldap_modify($con,$records[0]["dn"],$entry) === false){
    $message[] = "E200 - Your password cannot be change, please contact the administrator.";
  }
  else { 
    $message[] = " Your password has been changed. "; 
    //mail($records[0]["mail"][0],"Password change notice : ".$user,"Your password has just been changed."); 
    } 
}  

?>

OpenLDAP 有一个专门为此而设计的“独特性”覆盖。您通过 slapd.conf 加载它并配置您需要哪些属性是唯一的。

Ldap 不支持对除可分辨名称之外的字段的唯一约束。您可以搜索这些字段并使用 or 条件在一个查询中执行此操作,但您不会受到 100% 的保护。两个人可以同时提交相同的值,并且可能出现重复的时机恰到好处。这是一个过滤器示例,它将搜索姓名或电子邮件。

(|(&(givenname=joe)(sn=smith))(mail=joe.smith@example.com))

如果您受到打击,您可能会有重复。
