Since Cygwin release 1.3.3, applications that are members of the
Administrators group and have the <command>Create a token
object</command>, <command>Replace a process level token</command> and
<command>Increase Quota</command> user rights can switch user
context without giving a password by just calling the usual
<command>setuid</command>, <command>seteuid</command>,
<command>setgid</command> and <command>setegid</command> 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.
<command>setgid</command> and <command>setegid</command> functions.

<para>
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.
On NT and Windows 2000 the <systemitem
class="username">SYSTEM</systemitem> user has these privileges and can
run services such as <command>sshd</command>. However, on Windows 2003
<systemitem class="username">SYSTEM</systemitem> lacks the
<command>Create a token object</command> right, so it is necessary to
create a special user with all the necessary rights, as
well as <command>Logon as a service</command>, to run such services.
For security reasons this user should be denied the rights to logon
interactively or over the network. All this is done by configuration
scripts such as <command>ssh-host-config</command>.

is typically not possible to access network drives.
