Windows integrated authentication for "send mail" action

[ASolovey]

Hi,

It seems that VBP does not support Windows integrated authentication for "send mail" action. Is that true?

If this is the case do you plan to support it in the future?

Best regards,
Alex.

I'm not sure how the Send Mail action would use Windows Integrated Authentication -- AFAIK, that feature doesn't have anything to do with SMTP.

I didn't go that far to investigate technical explanations of what's happening.

I have AD domain environment with Exchange 2007 server. One of authentication options it supports for Receive Connector is "windows integrated authentication".

This option allows programs use default domain credentials to authenticate to Exchange for sending mail without specifiying plain text credentials.

For example, .NET class SmtpClient has property UseDefaultCredentials that allows sending mail programmatically and authenticate in the way I described. It does work.

The issue I'm researching is to make VBP "send mail" action to authenticate to Exchange without storing name and password in the step properties.

Alex.

That appears to be a Microsoft-specific extension (http://download.microsoft.com/download/9/5/e/95ef66af-9026-4bb0-a41d-a4f81802d92c/%5BMS-SMTP%5D.pdf) which isn't supported by the networking component used in VBP, but we'll add it to the request list to consider supporting in the future.
