Question

我无法使用LDAP对用户进行身份验证。我有以下细节：

URL=ldap://10.10.10.10:389 
LDAP BASE:DC=lab2,DC=ins 
LDAP Bind Account: CN=Ldap Bind,OU=Service Accounts,OU=TECH,DC=lab2,DC=ins 
LDAP Bind Account Pw: secret

我可以使用上述详细信息搜索sAMAccountName值，但是如何使用用户名和密码验证用户？
如果您按照我之前的问题进行操作，那么您就会明白，我已成功连接到LDAP服务器但无法对其进行身份验证。
用户进行身份验证：

user: someusername
password: somepwd

我无法使用'somepwd'连接到LDAP服务器，我应该如何使用someusername。我能够将给定用户搜索为sAMAccountName。

这是我在各个地方找到的东西的混搭。如果您不想使用UnboundID SDK，它应该让您沿着正确的路径前进。这不是生产质量，如果您的商店支持，您可能希望在此处添加SSL内容

public static Boolean validateLogin(String userName, String userPassword) {
    Hashtable<String, String> env = new Hashtable<String, String>();


    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, "ldap://" + LDAP_SERVER + ":" + LDAP_SERVER_PORT + "/" + LDAP_BASE_DN);

    // To get rid of the PartialResultException when using Active Directory
    env.put(Context.REFERRAL, "follow");

    // Needed for the Bind (User Authorized to Query the LDAP server) 
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.SECURITY_PRINCIPAL, LDAP_BIND_DN);
    env.put(Context.SECURITY_CREDENTIALS, LDAP_BIND_PASSWORD);

    DirContext ctx;
    try {
       ctx = new InitialDirContext(env);
    } catch (NamingException e) {
       throw new RuntimeException(e);
    }

    NamingEnumeration<SearchResult> results = null;

    try {
       SearchControls controls = new SearchControls();
       controls.setSearchScope(SearchControls.SUBTREE_SCOPE); // Search Entire Subtree
       controls.setCountLimit(1);   //Sets the maximum number of entries to be returned as a result of the search
       controls.setTimeLimit(5000); // Sets the time limit of these SearchControls in milliseconds

       String searchString = "(&(objectCategory=user)(sAMAccountName=" + userName + "))";

       results = ctx.search("", searchString, controls);

       if (results.hasMore()) {

           SearchResult result = (SearchResult) results.next();
           Attributes attrs = result.getAttributes();
           Attribute dnAttr = attrs.get("distinguishedName");
           String dn = (String) dnAttr.get();

           // User Exists, Validate the Password

           env.put(Context.SECURITY_PRINCIPAL, dn);
           env.put(Context.SECURITY_CREDENTIALS, userPassword);

           new InitialDirContext(env); // Exception will be thrown on Invalid case
           return true;
       } 
       else 
           return false;

    } catch (AuthenticationException e) { // Invalid Login

        return false;
    } catch (NameNotFoundException e) { // The base context was not found.

        return false;
    } catch (SizeLimitExceededException e) {
        throw new RuntimeException("LDAP Query Limit Exceeded, adjust the query to bring back less records", e);
    } catch (NamingException e) {
       throw new RuntimeException(e);
    } finally {

       if (results != null) {
          try { results.close(); } catch (Exception e) { /* Do Nothing */ }
       }

       if (ctx != null) {
          try { ctx.close(); } catch (Exception e) { /* Do Nothing */ }
       }
    }
}

Answer 2

LDAP连接以anonymous开始。要更改连接的授权状态，请使用BIND请求。 BIND请求采用两种形式，“简单”或“SASL”。 “简单”BIND请求采用可分辨的名称和密码。 BIND请求应通过安全连接传输，或使用StartTLS扩展请求提升为安全连接的非安全连接。

使用UnboundID LDAP SDK：

// exception handling not shown
LDAPConnection ldapConnection = new LDAPConnection(hostname,port);
BindRequest bindRequest = new SimpleBindRequest(username,password);
BindResult bindResult = ldapConnection.bind(bindRequest);
if(bindResult.getResultCode().equals(ResultCode.SUCCESS)) {
   /// successful authentication
}
ldapConnection.close();

We have several JNDI Samples这可能会有所帮助。

Answer 4

尝试使用它，对我有用

public static Boolean validateLogin(String userName, String userPassword) {
    Hashtable<String, String> env = new Hashtable<String, String>();


    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, "ldap://" + LDAP_SERVER + ":" + LDAP_SERVER_PORT + "/" + LDAP_BASE_DN);
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.SECURITY_PRINCIPAL, userName + "@" + LDAP_SERVER);
    env.put(Context.SECURITY_CREDENTIALS, userPassword);

    DirContext ctx;
    try {
       ctx = new InitialDirContext(env); //throw exception, if username-password not correct
       return true;
    } catch (Exception e) {
        return false;
    }
}
