You do what?   You mean you, for example:

 mkdir ~/suid-test-dir
 chmod 777 ~/suid-test-dir
 sudo chown daemon.daemon ~/suid-test-dir
 sudo chmod u+s,g+s ~/suid-test-dir
 touch ~/suid-test-dir/file

Now what are the user and group set on the file?

I see the file's "user" still set to me (i.e. setuid on dir didn't work), 
though the files "group" is set to 'daemon' (i.e. setgid on dir does work).

You are saying that on centos, both the user and group of 'file' are
*both* set to 'daemon'?
