OK.

As I said, I have both an admin and a normal account that show the same
behaviour (it makes no difference if the admin account is used with
elevated privileges or not).

You're on to something.  I have over 500 groups in my token in the old
domain, but only half of those end up in the token when I'm logged in on
the machine in the new domain (at least as far as Cygwin is concerned as
obviously I can still access the files when I'm actually trying).  I
scheduled an audience with one of the AD guys some time next week, he
thinks he can explain why that happens and hopefully it's something that
can be fixed on the AD side.  Eventually I'll have my account migrated
to the new domain later this year anyway at which point these sort of
problems should go away, but at least for the next two months I'll have
to stick it out.

Achim.
