I'm using 2.72, with a backend of MS SQL Server (we need encryption at rest, and already have a license for MS SQL Server). I built a library to handle json-rpc requests to limesurvey for our old version of the limesurvey (2.5), with a back end of MySQL.
I'm not sure if any of that has an impact on my current problem. But I've been trying to connect to the new instance of Limesurvey (2.72), and I can successfully get a session key, but I am unable to use any of the other functions available under the json=rpc (export_responses, list_questions). I get "status":"No Permission". I've double checked to make sure that the users who are being used to log in have essentially ALL of the permissions. But, for the life of me, I can't get it to allow me to download the responses.
Using the same user logins, I am able to download the responses no problem from the web interface.
