新创建的用户无法从RockMongo登录

Question

这里是我用mongo shell创建的示例用户，

{
   "_id": "admin.root",
   "user": "root",
   "db": "admin",
   "credentials": {
     "MONGODB-CR": "81e657aa9d80e314f75b9271216262fc" 
  },
   "roles": [
     {
       "role": "readWriteAnyDatabase",
       "db": "admin" 
    },
     {
       "role": "userAdminAnyDatabase",
       "db": "admin" 
    },
     {
       "role": "dbAdminAnyDatabase",
       "db": "admin" 
    },
     {
       "role": "clusterAdmin",
       "db": "admin" 
    } 
  ] 
}

您能帮我解决一下如何为rock mongo添加新用户吗？
