VPN Client auto login

[nvandoni1970]

I need to automate the login process of a Cisco VPN Client version 5.0.07.0440. I've tried using a command line like this but there is something wrong:

vpnclient.exe connect MyVPNConnection user username pwd password

This starts the connection but then a User Authentication dialog is shown, asking for username, password and domain. Username and password are already filled, domain is not necessary.

To continue I must press the OK button.

Is there a way to not show the dialog and automatically login into the vpn?

I need to do this also programmatically in C# or Delphi.

Any solution for this?  How can I pass in a blank domain parameter so I am automatically logged in instead of receiving the log-in dialog asking for the domain?
