Azure ACS with Office 365 as IdP

Hi, I'm having an issue setting up ACS to point at Office 365 as my Identity provider.

I used the following Guide to set things up. msdn.microsoft.com/en-us/library/Dn440559(v=NAV.70).aspx

Take note that this includes using the windows azure module for windows power shell to set up a service principal for the ACS(from my understanding this should have been the step that alleviates the below error...).

So far My App hits the ACS, with itself as the realm parameter, then goes on to Office 365 for authentication with the ACS as the realm and return URL. Successful Authentication occurs but after I'm presented the following error:

I feel like I'm missing something small to get O365 to direct back to my ACS properly. Anyone have any ideas?
