To be able to switch user context on the command line your login
needs special user rights. Read /usr/doc/Cygwin/inetutils-1.3.2.README
which contains some details. Additionally don't use `su' but `login'
to switch the user because it's really ported while su isn't.
To understand the interaction of NT and Cygwin security using the
`ntsec' option I suggest reading the online documentation
http://cygwin.com/docs.html, especially the `ntsec' documentation
