Question

我对使用LDAP的Spring Security来说还很陌生，我正在尝试使用LDAP服务器（FreeIPA）上密码已过期的用户进行身份验证。

我似乎无法触发任何密码过期异常等。“密码策略响应控件”始终返回null。...

这是我的代码，也许我做错了什么。如何处理密码策略错误？他们目前根本不会开火。

<bean id="freeIpaContextSource" class="org.springframework.security.ldap.ppolicy.PasswordPolicyAwareContextSource">
    <constructor-arg value="${logon.freeipa.zone.ldap.connection.url}"/>
    <property name="base" value="${logon.freeipa.zone.user.dn.base}"/>
</bean>

<bean id="freeIpaLdapTemplate" class="org.springframework.security.ldap.SpringSecurityLdapTemplate">
    <constructor-arg name="contextSource" ref="freeIpaContextSource"/>
</bean>

我有一个自定义的LdapAuthenticator，下面使用ldaptemplate来验证用户身份。

@Override
public DirContextOperations authenticate(Authentication authentication) {
    checkForIllegalStateDuringAuthentication(authentication);
    logger.info(String.format("*** Beginning to authenticate against LDAP zone %s ***", authorizationZone.getName()));
    zoneAuthenticationService.saveRequestDataInSession((UsernamePasswordAuthenticationToken) authentication, authorizationZone.getName());
    CollectingAuthenticationErrorCallback errorCallback = new CollectingAuthenticationErrorCallback();
    boolean isAuthenticated = false;
    String userName = authentication.getName();
    String password = authentication.getCredentials().toString();
    String filterLookup = buildLDAPFilterLookupString(userName);
    if (StringUtils.isNotBlank(password)) {
        logger.info(String.format("*** Attempting authentication for user %s ***", userName));
        try {
            isAuthenticated = ldapTemplate.authenticate(StringUtils.EMPTY, filterLookup, password, errorCallback);

        } catch (Exception exception) {
            errorCallback.execute(exception);
        }
    }
    if (!isAuthenticated) {
        if (errorCallback.getError() == null) {
            errorCallback.execute(new AuthenticationException(null));
        }
        //Any LDAP exception caught are stored inside the errorCallBack for use later to display an appropriate error.
        logger.error(String.format("*** Authentication for user %s has failed. Exception has occurred while system performed LDAP authentication. ***", userName), errorCallback.getError());
        throw new LdapAuthenticationException(errorCallback.getError().getMessage(), errorCallback.getError());
    }
    logger.info(String.format("*** Authentication for user %s has succeeded ***", userName));
    return new DirContextAdapter(buildAuthenticatedDN(userName));
}

无论我做什么，我都无法获得任何密码策略错误来返回。据我了解，您在尝试进行身份验证时需要使用PasswordPolicyControl设置请求控件，但是我从服务器上从未收到任何响应控件。我已经尝试实现以下类似的方法，但是在任何方面都没有运气。

LdapContext context = (LdapContext)ldapTemplate.getContextSource().getContext(buildAuthenticatedDN(userName).toString(), password);
Control[] rctls = new Control[]{new PasswordPolicyControl(false)};
context.reconnect(rctls);
PasswordPolicyResponseControl ctrl = PasswordPolicyControlExtractor.extractControl(context);
//ctrl is always null
 if (ctrl.isExpired()) {
                throw new 
PasswordPolicyException(ctrl.getErrorStatus());
            }

我在做什么错？我为此非常努力，任何帮助将不胜感激。

如果您的客户确实发送了正确的响应控制，则可能会遇到此问题（已存在7年了）：

#1539 [RFE] Add code to check password expiration on ldap bind

IIRC FreeIPA 仅在Kerberos预身份验证（kinit）期间强制执行密码过期。

LDAP Spring Security未引发密码策略错误
