RDS stands for Remote Development
Services and is a proprietary protocol that is built into Studio. RDS
does everything that FTP does, and also enables developers to browse
server databases, debug remote applications, and use server-side source
control. The RDS server also manages security. The RDS server is always
the ColdFusion Server.
Macromedia did not choose to make RDS
work through sandbox authentication in ColdFusion MX as they did in
previous versions of ColdFusion. This means that RDS can't be enabled
securely in a shared environment. Only one username and password per
server is currently available for RDS, which gives System Administrator
access. This means every user on a ColdFusion MX server would have
System Administrator access, and in a shared hosting environment, this
is unacceptable. We have no ETA on when Macromedia will allow multiple
usernames and passwords per server for the shared hosting environment.
