使用Java的SSL上的LDAP [英] LDAP over SSL with Java
本文介绍了使用Java的SSL上的LDAP的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
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连接并使用以下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，并且错误与证书有关.
then the program fails and the error is about the certificate.

那我该怎么解决这个问题?
So, what can I do to solve this problem?
推荐答案
起因:sun.security.validator.ValidatorException:PKIX路径构建失败:sun.security.provider.certpath.SunCertPathBuilderException:无法找到到请求目标的有效认证路径
Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
您的客户端信任库不信任LDAP服务器的证书.您需要通过CA对其进行签名，或者将其从服务器导出到所有客户端信任库中.最终使签名更容易和便宜.
Your client truststore doesn't trust the LDAP server's certificate. You need to either get it signed by a CA or else export it from the server into all the client truststores. It is ultimately easier and cheaper to get it signed.
