Spring LdapContextSource忽略SSLSocketFactory

Question

Spring-Ldap 1.3.1

为了用TLS测试spring，我创建了一个CustomSSLSocketFactory类，接受所有证书(我知道这个安全性问题)。

但是，运行测试将导致

PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

启用SSL调试后，将记录标准信任存储被认为是：

trustStore is: [path_to_jre]\cacerts
trustStore type is : jks
trustStore provider is : 
init truststore

以下是测试的执行方式：

    LdapContextSource lcs = new LdapContextSource();

    lcs.setBase("[base]");
    lcs.setUserDn("[userDn]");
    lcs.setPassword("[password]");
    lcs.setPooled(false);
    lcs.setUrl("ldaps://[server-address]:636");

    DefaultTlsDirContextAuthenticationStrategy strategy = new DefaultTlsDirContextAuthenticationStrategy();
    strategy.setShutdownTlsGracefully(true);
    strategy.setSslSocketFactory(new CustomSSLSocketFactory());  // <-- not considered at all
    strategy.setHostnameVerifier(new HostnameVerifier(){

        @Override
        public boolean verify(String hostname, SSLSession session){

            return true;
        }
    });

    lcs.setAuthenticationStrategy(strategy);
    lcs.afterPropertiesSet();
    lcs.getContext("[principal]", "[credential]");

对于另一个测试，我像这样扩展了LdapContextSource：

public class ExtLdapContextSource extends LdapContextSource{

    public DirContext getContext(String principal, String credentials) {

        getAnonymousEnv().put("java.naming.security.protocol", "ssl");
        getAnonymousEnv().put("java.naming.ldap.factory.socket", "[package].CustomSSLSocketFactory");
        return super.getContext(principal, credentials);
    }
}

握手比预期的要好，但是出现了另一个错误：

javax.naming.NamingException: [LDAP: error code 1 - 00000000: LdapErr: DSID-0C090DF2, comment: TLS or SSL already in effect, data 0, v1db1

at org.springframework.ldap.core.support.AbstractContextSource.getContext(AbstractContextSource.java:109)

因此，问题是:如何正确设置spring以使其使用所提供的SSLSocketFactory？

Answer 1

因为ldaps，它实际上失败了。如果相应地设置了信任存储，则异常显示不能建立TLS/SSL，因为它已经在运行(因此不能组合ldaps-URL和DefaultTlsDirContextAuthenticationStrategy )。

而且，无论StartTLS是否在端口389上工作，似乎都依赖于目录。

Answer 2

若要修复错误，请使用SimpleDirContextAuthenticationStrategy而不是DefaultTlsDirContextAuthenticationStrategy
