<para>Given a pointer to a passwd entry of a user and a cleartext password,
returns a HANDLE to an impersonation token for this user which can be used
in a subsequent call to <function>cygwin_set_impersonation_token</function>
to impersonate that user. This function can only be called from a process
which has the required NT user rights to perform a logon.</para>
