Thanks Joe,

You have caught an important typo there, many thanks! In the first upload
of the document (draft-dahm-opsawg-tacacs-00.txt), we used STARTTLS to
upgrade the connection type. Post discussions in Prague, we reverted to
using a separate port for TLS, and documented in the second upload
(draft-dahm-opsawg-tacacs-00.txt). However, I neglected to remove the
packet type for the STARTTLS from the enumeration, so thanks for the
catch. It will be removed on next upload.

Just to confirm, we are proposing separate port rather than STARTTLS.

To your very valid question: in the end, we elected not to add a new
version because we are looking to keep the content of the protocol the
same as the original draft spec (although deprecating some less secure
features). Besides the adoption of a separate port for TLS, this should
help avoid breaking current deployments.

Many Thanks,

Regards,

Thorsten, Andrej, Doug.
