yep

true, but that doesn't mean that aren't needed! If you apply that same
logic to other attributes you'll soon see the problem with the
argument. For example, isMemberOfPartialAttributeSet is also a 'may',
but if you don't have it you'll break RODC functionality. Similarly,
linkID is also a 'may', but it you don't have it you'll break all
linked attributes. The same is true for lots and lots of attributes.

The must/may attributes in the schema have very little to do with
whether an attribute is important or not :-)

which I think is an omission that needs fixing :-)

I strongly suspect that having different values for adminDescription
than what windows does will not break any applications. 

I am less certain about adminDisplayName, and I would not be surprised
if there were badly written apps (maybe even some MS apps?) that rely
on those values.

you probably just need to install the codec. The x264 (a free varient
of H.264) codec for windows is here:

  http://sourceforge.net/projects/x264vfw/files/

I also suspect it will work with a licensed H.264 codec, but I haven't
tested that. The Apple quicktime plugin should play it for example.

Media codecs are a real mess :-)
