<sect2 id="ntsec-release1.3.3"><title>New since Cygwin release 1.3.3</title>
<para>
Since Cygwin release 1.3.3, applications having the
<command>Create a process level token</command> user right 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.
</para>
<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.
