Constantly getting 401 errors in loopback when using User Model

I am new to loopback, and I cannot properly extend the user base model. Although in the explorer it shows that it is extended, but all the APIs give error 401. ex. In the usual way I get / for users I get ..

{
  "error": {
    "name": "Error",
    "status": 401,
    "message": "Authorization Required",
    "statusCode": 401,
    "code": "AUTHORIZATION_REQUIRED",
    "stack": "Error: Authorization Required"
  }
}

I went through all the links and questions, but none of them work for me. I posted correctly: true in model-config for the extended User Model and written by acls etc., but none of them work. I also raised a git question for strongloop: https://github.com/strongloop/loopback/issues/1809 . Any taps will be awesome. Thank.

User.json is as follows:

{
  "name": "user",
  "plural": "users",
  "base": "User",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },

    "name": {
      "type": "string",
      "required": true
    },

      "type": "string",
      "required": true
    },
    "password": {
      "type": "string",
      "required": true
    },
    "phone": {
      "type": "string"
    }
  },
  "validations": [],
  "relations": {
    "question": {
      "type": "hasMany",
      "model": "question",
      "foreignKey": ""
    }
  },
  "acls": [
    {
      "accessType": "*",

      "principalId": "$everyone",
      "permission": "DENY"
    },
    {
      "accessType": "*",
      "principalType": "ROLE",
      "principalId": "admin",
      "permission": "ALLOW"
