[Ugur Yilmaz]

I am using JIRA 6.4.1 and i tried several things,  did not worked.

with rest api i am trying to get all of 'jira-users', but api returns only 50 users 

 8080/rest/api/2/group?maxResults=1000&groupname=jira-users&expand=users

I tried:,

8080/rest/api/2/group/member?groupname=jira-software-users

result is 

null for uri

 also:

8080/rest/api/2/group?groupname=jira-users&expand=users&startAt=0&maxresult=250

result is same, only 50 users...
