LDAP身份驗證問題

Question

我必須連接到LDAP，但我無法使用Java代碼進行連接，並且使用LDAPAdmin工具正在進行連接。

String url = "ldap://host name:389"; 
ldapEnv.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory"); 
ldapEnv.put(Context.PROVIDER_URL, url); 
ldapEnv.put(Context.SECURITY_AUTHENTICATION, "simple"); 
ldapEnv.put(Context.SECURITY_PRINCIPAL, "CN=username"); 
ldapEnv.put(Context.SECURITY_CREDENTIALS, "#1223"); 

ERROR

Search error: javax.naming.AuthenticationException: [LDAP: error code 49 - 
    80090308: LdapErr: DSID-0C0903CF, comment: AcceptSecurityContext error, data 52e, v2580 

Answer 1

看一看這裏的錯誤代碼 - http://www-01.ibm.com/support/docview.wss?uid=swg21290631

數據52E - 根據鏈接，52E表示無效憑證。
