This is application-specific.  Some use host/fqdn as their service
principal; some use an app-specific principal; some have configurable
behavior.  What ftp server are you using?

You need to have one in *some* keytab on the server.  Unless otherwise 
configured, this should be krb5.keytab.

Um... no.  Kerberos *authenticates* users, so that the server has
assurance of the client's identity.  It says nothing about what access
they should be granted (authorization), just determines who they are
(authentication).
