Bug with multiple users with allowed_users attribute

[Sliim]

I have a bug when I want to set allowed_users for multiple users :
Example :

"user_ssh_keys": {
      "data_bag": "ssh_keys",
      "users": {
        "user1": {
          "authorized_users": [
            "foo",
            "bar"
          ]
        },
        "user2": {
          "authorized_users": [
            "foo"
          ]
        }
      }
    }

In this case, user1 will have correct authorized keys from foo & bar data bag items.
But the user2, which should have only the foo key, inherit of user1 allowed users. So instead of having only the public key for foo, there is also the bar public key and a duplicate foo public key added to the authorized_keys file..

Any idea?
