I'm having trouble finding what permission I'm missing for a particular group in PDM.  When a user in this group drags files into the vault, they show as grayed out local files, and nothing happens when you right click> 'Add to File Vault'.  There's no error message, and the file stays gray.  I've checked the folder and state permissions, and the Adding Files settings (that the file type is listed as one that should be added).  There's nothing in the log indicating an error or even an information entry about what's happening.  Any ideas?
