I have using the 30 day trial of ESRI Maps for MicroStrategy.
I have deployed the plugin to \MicroStrategy\Web ASPx\plugins\em4mstr.
My Settings File:
arcgisAuthType: "user", //or "app"
arcgisAppId:"<App ID pasted here>",
My MicroStrategy Web URL http://01hw498423.india.tcs.com/MicroStrategy/asp/ is on the intranet.
Whenever, I try to see the widget properties for a 'ESRI Maps for MicroStrategy widget' on a MicroStrategy dashboard, I get a popup with a 'Invalid redirect_uri Error: 400' error.
I also get an Oauth HTTP 400 window on some occassions. MicroStrategy Web is running on IIS & ASP.NET on a Windows Server 2008 R2 Enterprise box.
