I've looked at the Login page, Login.aspx.

What I want to do is bypass this login page and call the launch messenger directly passing in the username with a known username from the database.

I have tried calling (from Login.aspx)

   FormsAuthentication.RedirectFromLoginPage("user451", false);

with the rest of btnLogin_Click commented out.

 

This appears to work OK, logs you so that you get the username at the top of the page and a logout button, but when I select Messenger, it launches - but it is not logged in - and I get a anonymous login not allowed message.

 

Any advice much appreciated.
