Plugin to make multiple ipa calls via one remote procedure call
To run this code in the lite-server
curl -H "Content-Type:application/json" -H "Accept:application/json" -H "Accept-Language:en" --negotiate -u : --cacert /etc/ipa/ca.crt -d @batch_request.json -X POST http://localhost:8888/ipa/json
where the contents of the file batch_request.json follow the below example
{"method":"batch","params":[[
{"method":"group_find","params":[[],{}]},
{"method":"user_find","params":[[],{"whoami":"true","all":"true"}]},
{"method":"user_show","params":[["admin"],{"all":true}]}
],{}],"id":1}
The format of the response is nested the same way. At the top you will see
"error": null,
"id": 1,
"result": {
"count": 3,
"results": [
And then a nested response for each IPA command method sent in the request
