春季包1.3.1
为了使用TLS测试spring-ldap,我创建了一个接受所有证书的CustomSSLSocketFactory类(我知道与此有关的安全性问题)。
但是运行测试会导致
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
启用SSL调试后,会记录认为标准信任库:
trustStore is: [path_to_jre]\cacerts
trustStore type is : jks
trustStore provider is :
init truststore
这是执行测试的方式:
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

因此问题是:如何正确设置spring-ldap才能使其使用提供的SSLSocketFactory?
最佳答案
实际上由于ldaps-URL而失败。如果相应地设置了信任库,则异常表明无法建立TLS / SSL,因为它已经在运行(因此,ldaps-URL和DefaultTlsDirContextAuthenticationStrategy无法合并)。
同样,StartTLS是否在端口389上起作用似乎也取决于目录。
