Here is my guess: The IAC servlet is calling the IACauthentication activity and version 7.3.1 is more secure.
I'm aware some work were done to increase security on Mashup so that it doesn't work straight out of the box as this could leave a security hole if customer were not aware about it. I can't recall exactly what was made.
As a start, try customizing the authentication activity, make sure it is available for the unauthenticated access group, make sure it run by adding logging and even hardcode username/password there.
