Some features that might be desired further down the road: - Authentication before the server starts a new session and/or reveals information about it to the client. There are possible information security and denial of service issues here. - Redirection to another host > +=================== =================== =================================== > +No. of bytes Type Description > +=================== =================== =================================== > +1 ``U8`` *length of username* 256 bytes probably covers most user names, but I'd bet it doesn't cover all. For example, we've seen some cases where a LDAP dn is used as a user name and that can often exceed 256 bytes.
