Jira Rest Api for getting full user list
===

How can I get the list of all users using Jira Rest Apis.

I have tried:-

    /rest/api/latest/user/search?username=

Here I tried with blank username string but it doesn't return full user list. We only get some results when username is of at-least 1 length.

How can I get full users list from Jira rest API's ??
