I don't know which document you're referring to, but the first paragraph
of /usr/share/doc/Cygwin/login.README says
Under NT/2K/XP, login(1) is _not_ supposed to work on the command line
to change user context! Though you're able to tweak user permissions
to get login(1) working that way, that's NOT officially supported.
However, I see that xinetd does not work as it should. It also
misteriously dies with some sort of permission denied message. So when I
did a xinetd -d to see the transcript of an attempt to telnet, I saw
something similar to login failure. So I decided to try a simple
experiment with login. But I really need inetd/telnet/ftp to work.
From your cygcheck, you have no services installed. How are you running
xinetd? You can't just run it as "xinetd &" because under Windows,
regualr user accounts do not have the privileges necessary to switch
user credentials. You need to install it as a service running as
SYSTEM. Services are the analog of daemons in the unix world.

Brian,
Thank you for raising the important point of services. I am not much of
an expert in windows and thus did not even know about "services" package
or its need. I also do not know much about SYSTEM/ntsec and how win xp
works. Thus I expected setup.exe to install services or anything else
needed by deafult when I choose inetd/xinetd. Thus I did not know that I
need to run the daemons any different.
My fault in not reading /usr/share/doc/Cygwin/login.README is due to the
way I looked for docs. In Linux the docs are placed under
/usr/share/doc/<command_name>. Thus I looked for /usr/share/doc/login...
I should have done a find. I will be more careful next time.
Regards
Ramesh
