Sorry, but I guess you missed the fact that I did not mention
_passwordless_ authentication with any word.

sshd _did_ ask me for a password. Nevertheless, after entering
the password my usual home dir //bierfass/dunkel was not available.
If Windows needs another password to access the network share,
too: Fine. I wouldn't like to enter the same password twice,
but it is still better than having no access to my data.


The link you had sent says

Since Cygwin release 1.3.3, applications having the Create a
process level token user right can switch user context without
giving a password by just calling the usual setuid, seteuid,
setgid and setegid functions. This is typically only given
to the SYSTEM user. However, this now allows to switch the
user context using e. g. rhosts authentication or (when
running sshd under SYSTEM account as service) public key
authentication.

An important restriction of this method is that a process
started under SYSTEM account can't access network shares
which require authentication. This also applies to the
subprocesses which switched the user context without a
password. People using network home drives are typically not
able to access it when trying to login using ssh or rsh
without password.

If this method was introduced with Cygwin 1.3.3, how did ssh
and rsh work before this release?
