I am running SharePoint 2013 integrated with SQL Server 2012 and SSRS but I've been having problems trying to deploy my reports from Visual Studio 2012 BIDS. Whenever I enter in my login credentials it just pops up and ask me for them once again. I've looked in the log files and here is what I see:

However, it doesn't make sense to me because with the same account I have tested manually deploying the reports by uploading them to their document library using the SharePoint web interface and everything works just fine.

I am using forms and Windows authentication together and I have tried using both a forms and a Windows account to deploy the reports and neither one works. Also, I have checked the well known DisableLoopBackCheck keys and confirmed that it is not the issue.
