Well, I just installed the bridge and aside from the issue that CPanel/WHM doesn't use username@domain.com login names, everything else works as stated...

This is really just a bridge for username syncronization --- so personally, I'm uninstalling it because I was hoping more of a solution to bring all the functionality of ClientExect (such as the entire purchase process) directly into Joomla, but that isn't the case with this (unless someone has some ideas on this aspect that I've not found yet).

ClientExec has so many different plugins available for different client control panel systems, hosting platforms, etc so I really don't see this project being more than just a username and account bridge between the two to "view" your account directly in Joomla...
