ASP.NET beta 2 -connecting to database

I want to change from one db to another one, but I do not understand how.

I have change the <connectionStrings> in web.config

An in the <asp:Login> form I cant see anything I can change;

<asp:Login ID="Login1" runat="server" FailureText="Feil Brukernavn eller passord prøv igjen"
LoginButtonText="Logg inn" PasswordLabelText="Passord" PasswordRequiredErrorMessage="Obs: skriv inn passord"
RememberMeText="Husk meg neste gang" TitleText="Logg inn" UserNameLabelText="Brukernavn:"
UserNameRequiredErrorMessage="Obs: skriv inn Brukernavn" DestinationPageUrl="~/members/Default.aspx" >
</asp:Login>


But det login page is still trying to log in on the old database?
Is it any place I have to change the database that I dont know about?

if you need it:
default
web.config
