only proxy server authentication is in clear text. However, many setups
have the same authentication for proxy-users as for system-users. Often
such authentication is performed over central LDAP-Server. Sure, it is a
fail of system administrator, if he allow such unecrypted authentication
over Internet. But I don't even give them a possibility to make such
mistake...
