Spring-Ldap 1.3.1

为了使用TLS测试spring-ldap，我创建了一个CustomSSLSocketFactory类，接受所有证书（我知道安全问题）。

然而，运行测试会导致

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

启用SSL-debug后，会记录标准信任库：

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

这是测试的执行方式：

    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);
    }
}

握手比按预期工作，但出现另一个错误：

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

所以问题是：如何正确设置spring-ldap以使其使用提供的SSLSocketFactory？

Answer 1

由于ldaps-URL，它实际上失败了。如果相应地设置了信任库，则异常显示无法建立TLS / SSL，因为它已在运行（因此无法合并ldaps-URL和DefaultTlsDirContextAuthenticationStrategy）。

此外，无论StartTLS是否在端口389上运行，它似乎都依赖于目录。

Answer 2

要修复错误，请使用SimpleDirContextAuthenticationStrategy代替DefaultTlsDirContextAuthenticationStrategy

Spring LdapContextSource忽略SSLSocketFactory
