You can also use 'dn' for the user to put in the dn in the login form (but usually is too long for user to remember or know).
  # :domain - Enter to keep users from having to enter the LDAP domain, usually in the form domain\username. Backslash will be appended automatically.
  # :try_sasl - Try to use SASL connection to server.
  # :sasl_mechanisms - Mechanisms supported are 'DIGEST-MD5' and 'GSS-SPNEGO'
