title: Remove all members from a group in WSO2 IS using SCIM endpoints
body: <p>I have created one group in WSO2 IS by using SCIM endpoint. Then i updated the group with some members. Now i want to remove all the members from the group, I have used the same update command to do this, But i couldn't remove all the members from the group. No errors are there.
  I have used the following curl commands to do this.</p>

  <pre><code>curl -v -k --user admin:admin --data "{"displayName": "groupname"}" --header "Content-Type:application/json" https://example.com:9443/wso2/scim/Groups
  </code></pre>
