LDAP通过JAVA而不提供密码 [英] LDAP via JAVA without providing password

问题描述

在C＃中，我写了下面的代码来连接到LDAP服务器并查询相同的内容。

in C#, I have written below code to connect to LDAP server and query the same.

String ldapUrl = "LDAP://...";
            DirectoryEntry entry = new DirectoryEntry(ldapUrl);
            DirectorySearcher dSearch = new DirectorySearcher(entry);

            String Name = "ravi";
            dSearch.Filter = "(&(objectClass=user)(sAMAccountName=" + Name + "))";

            foreach (SearchResult sResultSet in dSearch.FindAll())
            {
                String data =  "Login Name :" + (GetProperty(sResultSet, "cn")) + "\r\n" +
                    "First Name :" + (GetProperty(sResultSet, "givenName")) + "\r\n" +
                    "Middle Initials :" + (GetProperty(sResultSet, "initials")) + "\r\n" +
                    "Last Name : " + (GetProperty(sResultSet, "sn"));
            }

如果您注意到，我没有提供用户名和/或密码。我认为它使用登录用户凭据的操作系统登录LDAP服务器。

If you notice, no where I have provided the username and or password. I think it logs-in to the LDAP server using the OS logged in users credentials.

但是在JAVA中

String url = "ldap://localhost:10389";
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, url);
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(***Context.SECURITY_PRINCIPAL, "uid=admin,ou=system"***);
env.put(***Context.SECURITY_CREDENTIALS, "secret"***);

try {
    DirContext ctx = new InitialDirContext(env);
    System.out.println("connected");
    System.out.println(ctx.getEnvironment());

    ctx.close();

} catch (Exception ex) {
    System.out.println("error when trying to create the context");
}

java中是否有办法在不提供用户名的情况下绑定到LDAP服务器和密码？我尝试通过将Context.SECURITY_AUTHENTICATION设置为NONE来绑定，但是它们会抛出匿名登录的例外，不允许。我不知道如何使用匿名用户凭据，但操作系统已登录用户凭据。

Is there a way in java to bind to the LDAP server without providing the username and password? I tried bind to by setting the Context.SECURITY_AUTHENTICATION as NONE, but it them throws the exception for anonymous login not allowed. I don't what to use Anonymous user credentials but the OS logged in users credentials.

这是可能的以及如何实现？

is this possible and how?

问候，

推荐答案

我用JNI来调用C＃dll ...问题是JNI非常慢。每次通话大约需要15-20秒

I used JNI to invoke a C# dll... the problem is JNI is very slow. it is taking almost 15-20 sec per call
