Chaskiel,
In theory, upgrading client and/or server first should work. In
practice, krb5 is not heavily tested, not to say it is not tested at
all, but it have not changed in many years.
Add:
debug_auth 9
in amanda.conf on the server and in /etc/amanda/amanda-client.conf on
the client.
Retry the backup.
Post the complete dumper-*.debug file from the server and the complete
amandad-*.debug and sendbackup-*.debug files from the client.

I am trying to use amanda 3.3.5 on a rebuilt server, and my first
amdump run failed. estimates and such ran fine, but none of the
dumpers succeeded. Should this work, or do the clients have to be
upgraded first? Will new clients work with the old servers?

The sendbackup debug files on the client seem to be completely normal.
Thanks.
