Project 2010 and Project Pro 2007
Just a FYI since no one knew this from what i can tell already: If you are enabling BCM (Backwards Compatibility Mode) for project 2007 to connect to Project Server 2010, there are a few things you should know first. Right off the bat, clients have to be updated to Service Pack 2 . Next, when your setting up your project server, Note this key fact I could not find anywhere, and did not get hint about in the technet forms when i posted about my problems: You CAN NOT use Claims based authentication on your web application that is hosting Project Server 2010. The 2007 Client will not connect to the server. The 2010 client will connect with no problems. Quick and dirty, hope that helps everyone!
