Hi, a fairly basic question i think. 

I am currently trying to authenticate a user using the standard asp.net login control,

<asp:login id="testExample" runat="server" />

I have a created a member programaticallly which appears as expected in the database.  However, when trying to log in with the correct credentials, I receive an authentication unseccessful message within the control. I assume this is the default message for failure in a variety of conditions, but I can't seem to pinpoint the cause.

As I understand, Umbraco is set up so you can just drop this standard control into a template?  I must be missing something, I am just not sure where.  Any advice which might point me in the right direction would be appreciated.

Thanks,

Chris.
