我正在将LDAP认证添加到spring-boot应用程序中，所有设置都是相应的，即使提供了正确的凭据，我还是收到了“LDAP错误代码49 AcceptSecurityContext错误数据52 e v2580”错误。
我使用的是import javax.naming.Context;，并且已经提到了下面的代码。

String url = ldap_url;
String domain = ldap_domain;
String uname = request.getUsername();
String pwd = request.getPassword();
boolean authentication = false;
boolean error = true;
String msg;
String ldapSearchBase = "OU=TEST_OU, DC=DC2, DC=DC1";

// create env for initial context
Hashtable<String, String> env = new Hashtable<String, String>();
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, "CN=" + uname + "@" + domain + "," + ldapSearchBase);
env.put(Context.SECURITY_CREDENTIALS, pwd);
NamingEnumeration results = null;

try {
    LdapContext ctx = new InitialLdapContext(env, null);
    authentication = true;
    error = false;
} catch (NamingException e) {
    logger.error("LDAP error for :{NamingException}" + e);
    return ResponseEntity.ok(new ApiResponse(true, e.getMessage()));
} finally {
    if (!error) {
        msg = "Login success!!!";
    } else {
        msg = "Authentication failed!";
    }
}

logger.info("exitinig...");

if (authentication) {
    return ResponseEntity.ok(new ApiResponse(false, msg));
} else {
    return ResponseEntity.ok(new ApiResponse(true, msg));
}

错误捕获为NamingException。
