Just came across an interesting issue between the Integrated Video Tutorials and the domain Mapping Plugin. I run http://Brellabee.com and part of the service is to use the WPMU Domain Mapping plugin. Subscribers who try to access their videos when logged in through their main domain are then denied access to the video tutorials in their Dashboard. Even though they are essentially a sub domain of an authorised URL in my account.
The former domain can access the videos, but the second cannot.
Can't the Video Tutorial plugin check for the domain mapping plugin (with a function_exists() call), then pass the sub domain for authentication, not the mapped domain?
The current situation will not scale to hundreds and thousands of users all mapping their domains to my service.
I hope this explanation is clear.
