Requester can't log into mobile app

Requester can't log into mobile app

This past weekend I updated our SDP server to build 9100.  One of the big changes that I was hoping to leverage is the ability for Requesters to log into the mobile app.  I've set up my test user with an API key, but when I try to log in from the IOS app (v3.2) I get the following message:

"Error: Requesters are not allowed to use mobile application" 

Is there a bit I need to flip to allow this other than generating the user's API key?
