问题描述

以下代码可以正常工作:

The following code works fine:

public static void main(String[] args) {
    String userName = "admin";
    String password = "s3cret";
    Hashtable env = new Hashtable();
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, "ldap://192.168.10.45:389/dc=softwaredev,dc=local");
    //env.put(Context.SECURITY_PROTOCOL, "ssl");
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.SECURITY_PRINCIPAL, new String("softwaredev" + "\" + userName));
    env.put(Context.SECURITY_CREDENTIALS, password);

    DirContext ctx = null;
    NamingEnumeration results = null;
    try {
        ctx = new InitialDirContext(env);
        SearchControls controls = new SearchControls();
        controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
        results = ctx.search("", "(objectclass=person)", controls);
        while (results.hasMore()) {
            SearchResult searchResult = (SearchResult) results.next();
            Attributes attributes = searchResult.getAttributes();
            System.out.println(" Person Common Name = " + attributes.get("cn"));
            System.out.println(" Person Display Name = " + attributes.get("displayName"));
            System.out.println(" Person logonhours = " + attributes.get("logonhours"));
            System.out.println(" Person MemberOf = " + attributes.get("memberOf"));
        }
    } catch (Throwable e) {
        e.printStackTrace();
    } finally {
        if (results != null) {
            try {
                results.close();
            } catch (Exception e) {
            }
        }
        if (ctx != null) {
            try {
                ctx.close();
            } catch (Exception e) {
            }
        }
    }
}

如果我取消注释以下行:env.put(Context.SECURITY_PROTOCOL, "ssl"); 启用 SSL 连接并使用此 URL:

If I uncomment the following line: env.put(Context.SECURITY_PROTOCOL, "ssl"); to enable SSL connection and use this URL:

ldaps://192.168.10.45:636

然后程序失败，错误是关于证书的.

then the program fails and the error is about the certificate.

那么，我该怎么做才能解决这个问题呢?

So, what can I do to solve this problem?
