kerberos auth does not work for ftp traffic?

[Sean Boran <sean@xxxxxxxxx>]

Hi,

Kerberos is authenticating http/s traffic for me from certain client
addresses just fine.
However ftp is being rejected, does the browser+squid not auth ftp in
the same way as http?

If ftp does work with kerberos, is there a way (ACL) that ftp traffic
can be excluded from kerberos auth?

Thanks in advance,

Sean
