SharePoint Online remote Authentication from a Shared Server (c# code)

I would like c# code to programmatically authenticate to my SharePoint Online 2013 (like Office 365) site from a remote shared Windows server. I've tried various methods, but the most promising is using the "Client Object Model" SharePointOnlineCredentials. It works great on my PC, but fails ("FileNotFoundException: [login to view URL]") when I deploy to my server. • I have tried using this method: [login to view URL] • On my dev PC, I've installed SharePoint 2013 client object model assemblies (Client Components SDK) from [login to view URL]; which work perfectly on my PC • In Visual Studio 2012, I've referenced [login to view URL] and the [login to view URL] (C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\Client) • In Visual Studio, I am NOT able to add a reference for [login to view URL] (even though it is on my PC in the "C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\ISAPI" folder). • I have all 3 files of these files in my bin folder on the server: [login to view URL], [login to view URL], and [login to view URL] • My server is a shared/virtual server and does not have SharePoint installed. I cannot install software or edit the registry on the server. • I can solve the "FileNotFoundException: [login to view URL]" by providing a hard-coded file path to it in the bin folder, but then other issues occur beyond my capabilities. Perhaps it is looking for other dlls normally on PCs, but not on Windows Server. I need to authenticate on a server because after successful authentication, I have code that then programmatically extracts needed info from SharePoint using the REST API (not in scope of this project, I'll do this). Note that this work may not be easy (I've been trying to solve it for hours, but I'm not a programmer and I don't have any technical training), but I believe it is possible -- it works fine on PCs. I see several forum posts with other people having this issue, but I don't see anyone offering a simple solution. I will provide a guest account to my SharePoint Online account and ftp access to a subdomain on my server. Work may require: • Viewing code in [login to view URL] and [login to view URL] (using something like ILSpy) to understand how it does the authentication. Note that I cannot add [login to view URL] as a reference in VS and I can't view it in ILSpy "does not contain a managed assembly". But I'm not sure [login to view URL] is used because in the VS Debug output, I don't see that it is loaded. • Viewing network traffic via Fiddler (or similar) to understand the way it works on a PC I will release full payment with delivery of VS solution that successfully authenticates from my server. I will consider partial payment for a plan that appears likely to work.
