java - 为 Ldap 连接配置 Spring 安全性

coder 2023-05-12 原文

我必须配置 Spring 安全性以通过 LDAP 对用户进行身份验证。这是经理用户所在的子树:

ldaps://vldp.floal:636/CN=Administration,CN=fdam,DC=fg,DC=local

这就是用户所在的地方:

ldaps://vldp.floal:636/CN=ProxyUsers,CN=fdam,DC=fg,DC=local

所以我使用这个设置:

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception{
     auth.ldapAuthentication()
      .contextSource()
        .url("ldaps://vldp.floal:636/DC=fg,DC=local")
        .managerDn("CN=A0XXX32,CN=Administration,CN=fdam,DC=fg,DC=local")
        .managerPassword(password)
      .and()         
      .userSearchBase("CN=ProxyUsers,CN=fdam")     
      .userSearchFilter("(CN={0})")
      .ldapAuthoritiesPopulator(myAuthPopulator);     
}

问题是当我尝试通过用户登录时抛出异常，我收到此错误:

spring 参数存在问题，因为如果我使用 java 代码对用户进行身份验证，它就可以工作。我不知道问题出在哪里，你能帮帮我吗？

我进行了调试，这是错误之前的输出:

PS:如果使用 ldap 浏览器使用 CN=F67XXX7A,CN=ProxyUsers,CN=fdam,DC=fg,DC=local 它会绑定(bind)。

更新:如果我在没有 Spring 登录的情况下使用 java，我需要使用 Spring 并弄清楚如何配置它:

@Override
public void isAuthenticated(String username, String password) throws LdapException{
    if (databaseMatlabClientServices.getByUsersEnabled(username)== null)
        throw new LdapException("User doesn't exist into DART database. Please contact the administrator!");
    String dn="";;
    //First query to retriev DN
    Hashtable<String, Object> ldapEnv = new Hashtable<String, Object>();
    ldapEnv.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    ldapEnv.put(Context.PROVIDER_URL, env.getRequiredProperty(PROPERTY_NAME_LDAP_URL));
//Without authentication        ldapEnv.put(Context.SECURITY_AUTHENTICATION, "none");
    //With authentication to access to LDAP server
    ldapEnv.put(Context.SECURITY_AUTHENTICATION, "simple");
    ldapEnv.put(Context.SECURITY_PRINCIPAL, env.getRequiredProperty(PROPERTY_NAME_LDAP_NAME));
    ldapEnv.put(Context.SECURITY_CREDENTIALS, env.getRequiredProperty(PROPERTY_NAME_LDAP_PASSWORD));
    String[] returnAttribute = {"dn"};
    DirContext ctx = null;
    NamingEnumeration<SearchResult> results = null;
    try {
        ctx = new InitialDirContext(ldapEnv);
        SearchControls controls = new SearchControls();
        controls.setReturningAttributes(returnAttribute);
        controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
// without authentication on local server String filter = "uid=" + username ;
        String filter = "CN=" + username ;
        results = ctx.search(env.getRequiredProperty(PROPERTY_NAME_LDAP_USERSEARCHBASE), filter, controls);
        if (results.hasMore())
            dn = results.nextElement().getNameInNamespace();
        else 
            throw new LdapException("Wrong username. Please retry!");
    } catch (NamingException e) {
        throw new LdapException(e);
    } finally {
        try{
            if (results != null)
                results.close();             
            if (ctx != null) 
                ctx.close();
        }catch(Exception e){
            throw new LdapException(e);
        }
    }

    //Second query to try to access with obtained Dn and given password
    Hashtable<String, Object> authEnv = new Hashtable<String, Object>();
    authEnv.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
    authEnv.put(Context.PROVIDER_URL, env.getRequiredProperty(PROPERTY_NAME_LDAP_URL));
    authEnv.put(Context.SECURITY_AUTHENTICATION, "simple");
    authEnv.put(Context.SECURITY_PRINCIPAL, dn);
    authEnv.put(Context.SECURITY_CREDENTIALS, password);
    DirContext ctx2 = null;
    try {
        ctx2 = new InitialDirContext(authEnv);
    } catch (AuthenticationException authEx) {
        throw new LdapException("Authentication error. Password was wrong");
    } catch(Exception e){
        throw new LdapException(e);
    }finally {
        try{         
            if (ctx2 != null) 
                ctx2.close();
        }catch(Exception e){
            throw new LdapException(e);
        }
    }
}

更新@pczeus 代码: 要设置referral=follow，我使用了以下代码:

DefaultSpringSecurityContextSource contextSource = new DefaultSpringSecurityContextSource("ldaps://vldp.floal:636/");
contextSource.setUserDn("CN=A0XXX32,CN=Administration,CN=fdam,DC=fg,DC=local");
contextSource.setPassword(password);
contextSource.setReferral("follow"); 
contextSource.afterPropertiesSet();

LdapAuthenticationProviderConfigurer<AuthenticationManagerBuilder> ldapAuthenticationProviderConfigurer = auth.ldapAuthentication();

ldapAuthenticationProviderConfigurer
    .ldapAuthoritiesPopulator(myAuthPopulator)
    .userSearchFilter("(CN={0},CN=ProxyUsers,CN=fdam,DC=fg,DC=local)")
    .userSearchBase("")
    .contextSource(contextSource);

我收到了经典异常:

2016-04-07 09:34:41 [http-nio-8086-exec-4] ERROR o.s.s.w.a.UsernamePasswordAuthenticationFilter - An internal error occurred while trying to authenticate the user.

 ]; remaining name '/'

如果我添加 .userSearchBase("CN=ProxyUsers,CN=fgadam,DC=fg,DC=local") 我收到了

其中 DN 是 ''，为什么？

最佳答案

In AbstractContextSource (parent of LdapContextSource), the Javadoc for the setBase() method says the following: "Set the base suffix from which all operations should origin. If a base suffix is set, you will not have to (and, indeed, must not) specify the full distinguished names in any operations performed.". Since you specify the full DN for the userDN/filter, hence you must not specify the base.

尝试将 userSearchBase 设置为空字符串 ("")，或者将调用全部删除。

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception{
     auth.ldapAuthentication()
         .contextSource()
         .url("ldaps://vldp.floal:636/DC=fg,DC=local")
         .managerDn("CN=A0XXX32,CN=Administration,CN=fdam,DC=fg,DC=local")
         .managerPassword(password)
         .and()         
         .userSearchBase("")     
         .userSearchFilter("CN={0},CN=ProxyUsers,CN=fdam,DC=fg,DC=local")
         .ldapAuthoritiesPopulator(myAuthPopulator);     
}
