Create user via REST

Hi,

Currently I am evaluating syncope for our usage. I would need to do bulk user creation from REST. I started to create single user from REST client and it fails.

From postman, I tried to create a user with below inputs. I get '400 Bad Request'. If there is anything wrong in the format.

POST - http://135.249.22.223:8080/syncope/rest/users

Authorization:
Basic Auth - admin/password

Headers:
Content-type: application/json

Body:
{
"@class": "org.apache.syncope.common.lib.to.UserTO",
"creator": "admin",
"lastModifier": "admin",
"key": "rest1",
"type": "USER",
"realm": "/",
"status": "Active",
"auxClasses": [],
"plainAttrs": [],
"derAttrs": [],
"virAttrs": [],
"resources": []
}
