Will the SecureTcp Control work through
a proxy based firewall? If not, I can have my clients bypass the proxy.

I have written an application that connects to a secure site and it receives reports from a secure web site.It works fine at my location through a firewall. When I deploy the application to my client sites they receive the following error:

"An invalid username or password was used for
authentication or invalid security certificate was
used for authentication"

I know for sure that the client is using the right
user id and password and I don't use a client certificate for authentication. Why is this happening? I pass the user id and password through the http header. How can I reproduce this error?

thanks...

That error could mean one of two things:

1) Some part of the server's certificate is not valid, and you did not override the check using the Security property or in the Authentication event.

2) The server is not SSL and you are attempting to connect to it with the protocol set to something other than secureNone.

If the proxy supports SSL it may work if you choose explicit security.

Try all the different settings in the sample FTP listview app and see if any work.
