Hmm, anyone who can explain why i get a connection error whatever parameters i use in web.config?

During install i get this message:

No valid default database connection detected.
Standard Database setup option is unavailable

I have followed the procedure in the read.me file under \Documentation. (And tried the same setup as used on a running dnn5 installation)

From web.config:

<connectionStrings>
    <!-- Connection String for SQL Server 2005/2008   -->
    <add name="SiteSqlServer" connectionString="Server=(local);Database=DotNetNuke;uid=DnnUser;pwd=Dnn7Sql;" providerName="System.Data.SqlClient" />
  </connectionStrings>
  <appSettings>
    <add key="SiteSqlServer" value="Server=(local);Database=DotNetNuke;uid=DnnUser;pwd=Dnn7Sql;"/>
    ....

What about Object Qualifier, it is optional, should it be set?

If i connect to DotNetNuke db with DnnUser via sqlmanager i can create tables etc., so the sql 'things' must be ok.
