6. Kerberos

If Yafc is compiled with Kerberos, it tries to authenticate using Kerberos 4/5 without sending the password in cleartext. For anonymous logins, Kerberos is never used. The default protection level for data connections is clear, ie no encryption on transfers. Use the command prot (3.1.33 prot), to change the data protection level. Valid arguments are clear, safe, and private. Note that confidential protection is not supported in Kerberos 4. You can use the `prot' keyword (see section 5.0.1 Bookmark keywords) in the bookmarks file to automagically set the protection level for a specific host.
