k8s集群环境多副本pod无法登陆

**版本信息**
k8s version: 1.14.1
apollo version：1.7.1
traefik version: 1.7
helm chart version: 0.1.1

**问题描述**

参考这里：https://github.com/ctripcorp/apollo/wiki/%E5%88%86%E5%B8%83%E5%BC%8F%E9%83%A8%E7%BD%B2%E6%8C%87%E5%8D%97#241-%E5%9F%BA%E4%BA%8Ekubernetes%E5%8E%9F%E7%94%9F%E6%9C%8D%E5%8A%A1%E5%8F%91%E7%8E%B0
部署了apollo后，并集成了ldap(windows ad)，apollo-portal如果配置多pod副本，系统无法登陆，
修改为单副本的pod，就可以正常登陆。

看官方配置只有nginx ingress controller的例子，我们实际生成环境用的traefik ingress controller，我依照官方例子修改如下信息以后还是无法登陆；实际测试中通过chrome debug可以看出其实已经登陆成功，只是没有跳转到后台，不知道哪里的问题，还请帮忙解惑。

helm chart参考这里：https://github.com/ctripcorp/apollo/tree/master/docs/charts
