RDC on OS X stores license information in the directory
"/Users/Shared/Microsoft/RDC Crucial Server Information". The
cause of my problem is that RDC doesn't set permissions correctly
on this directory. So long as the user that originally ran RDC is
the one running the current session, all is well. But if another
user on the machine tries, it doesn't work.
The directory "/Users/Shared/Microsoft/" is owned by whichever
user first ran RDC, and by the group "wheel" On OS X, all users
are a member of the "wheel" group, unless they are explicitly
excluded. The problem is that "wheel" doesn't have write
permissions in "/Users/Shared/Microsoft/" or any of its
subdirectories.
