Functional Example: BDC ADF that connects to SQL database with embedded user id and password

I needed to wire up MOSS to a SQL database via BDC. For testing/POC purposes, I wanted to embed the SQL account user id and password in the ADF. Starting with this template (http://msdn2.microsoft.com/en-us/library/ms564221.aspx), I created an ADF that connects to a particular SQL server instance and logs in with a specific user id and password and shown in this snippet:

  <LobSystemInstances>
    <LobSystemInstance Name="ClaimsInstance">
      <Properties>
        <Property Name="AuthenticationMode" Type="System.String">PassThrough</Property>
        <Property Name="DatabaseAccessProvider" Type="System.String">SqlServer</Property>
        <Property Name="RdbConnection Data Source" Type="System.String">actual server\actual instance</Property>
        <Property Name="RdbConnection Initial Catalog" Type="System.String">actual initial catalog</Property>
        <Property Name="RdbConnection Integrated Security" Type="System.String">SSPI</Property>
        <Property Name="RdbConnection Pooling" Type="System.String">false</Property>
        
        <!-- These are the key values: -->
        <Property Name="RdbConnection User ID" Type="System.String">actual User ID</Property>
        <Property Name="RdbConnection Password" Type="System.String">actual Password</Property>
        <Property Name="RdbConnection Trusted_Connection" Type="System.String">false</Property>

      </Properties>
    </LobSystemInstance>
  </LobSystemInstances>

It is not a best practice, but it's useful for a quick and simple configuration for testing. This was surprisingly difficult to figure out. I never found a functional example with search keywords:

adf embedded userid and password
embed user id and password in adf
embed user id and password in adf bdc
sharepoint bdc primer
sharepoint embed user id and password in adf

</end>

The full exception text is: The LobSystemInstance Property 'AuthenticationMode' has a value that requires 'Integrated Security' in the connection string Apr. 25
	Jan D'Hondtwrote: Havie struggled with LobsystemInstance connection setup too. Used your comments to check if everything worked. My setting differs in that i have set 'Integrated security' to false instead of SSPI and 'rdbconnection Pooling' to true. My observation about Connection Pooling: since the connection string for any user of this BDC will be exactly the same, the same connection will be used over and over again and therefore can be efficiently pooled by the system. Thus saving overhead on the sql server side. Or is there something I overlooked? Nov. 26

And if my MS SQL is using windows authentication ? what would be the user id and password in this case? domain\user then my windows log on password? Dec. 7
