If you use Negotiate without SSL, any MITM can assume the Kerberos 
credentials after the initial GSSAPI exchange.  I would disable it by 
default for proxy auth too if there was any alternative, but there's not 
(you can't use SSL to the proxy).

You can override the default policy by using ne_add_*_auth() instead of 
ne_set_*_auth.
