我是一名大学生。现在,我正在做一个必须使用LDAP连接来验证登录过程中用户的用户名和密码的项目。所以,我的网站是用JSP开发的。我试图解决代码的错误,但我不能。我是否犯了一些错误?

try {
//Connect with ldap
new InitialLdapContext(env, null);
//Connection succeeded
System.out.println("Connection succeeded!");
} catch (AuthenticationException e) {
//Connection failed
System.out.println("Connection failed!");
e.printStackTrace();
}

我从运行代码中得到了这个错误信息。

这是重要的一句话: javax.naming.InvalidNameException:[LDAP:错误代码34 - 无效的DN]
你可以看看这里: https://wiki.servicenow.com/index.php?title=LDAP_Error_Codes
代表34的含义,但看起来你尝试使用的专有名称是不正确的。看起来你的校长可能格式不正确。在执行ldap身份验证时,请参阅oracle的本指南: http://docs.oracle.com/javase/jndi/tutorial/ldap/security/ldap.html
在设置环境条目的地方特别注意它的这一部分:
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "cn=S. User, ou=NewHires, o=JNDITutorial");
env.put(Context.SECURITY_CREDENTIALS, "mysecret");
答案 1 :(得分:2)
堆栈跟踪中的“javax.naming.InvalidNameException:[LDAP:错误代码34 - 无效DN]”是关键。您的LDAP服务器不喜欢您发送它的值。我建议完全限定用户名,例如cn = username,ou = some_container,o = mycompany。实际语法将由LDAP服务器驱动。
