This is a caveat of the default nsswitch configuration in Cygwin.
It uses home directories inside Cygwin's own directory tree by default and
name them after username without domain, but you can configure it to either
use a different home directory name or just use user's profile as home
directory. Which is, if you ask me, way more logical.

Be aware of the noacl flag for mounting directories outside Cygwin tree, or
you may surprise your Windows applications with less than trivial ACE setups
generated by Cygwin in "strict POSIX" mode.
