推荐答案
这是重要的一行：
javax .naming.InvalidNameException：[LDAP：错误代码34 - 无效DN]
This is the important line: javax.naming.InvalidNameException: [LDAP: error code 34 - invalid DN]
您可以在这里查看：
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。请参阅oracle关于ldap身份验证的指南：
for what 34 means, but it looks like the distinguished name you are trying to use is incorrect. It looks like your principal could be formatted incorrectly. See this guide from oracle on doing ldap authentication:http://docs.oracle.com/javase/jndi/tutorial/ldap/security/ldap.html
特别注意这部分地方他们设置了环境条目：
pay special attention to this part of it where they set up the environment entries:
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "cn=S. User, ou=NewHires, o=JNDITutorial");
env.put(Context.SECURITY_CREDENTIALS, "mysecret");
