Is there any way to construct an ACL that checks the authentication mechanism used (eg: radius/kerberos)? I want to allow radius authentication only for FTP users, since there is no FTP client (that I know of) that works with Scalquid using kerberos authentication, but I want to enable it only for FTP and not HTTP. Or even better, anybody knows of a graphical FTP client that can authenticate to Squid using kerberos?
