Sure it does.

Wow, that really should work.  One more thing:  Check permissions on
directories leading up to your $HOME (i.e.: /itc/data/home, /itc/data,
and /itc, maybe even /).  If any of those block your UID, you won't
be able to see /itc/data/home/user either.

/me pines for the olden days of Unix when this weren't so....
