Which CCS Standard support raw-based via agent-based data collector?

Dear All, 

    I install CCS Agent on windows 2008 R2 with MS SQL 2008 R2. I install windows agent and RBC(raw-based collector), ccsmssqltpi.exe, from installer media.

    After register agent and import. I found only windows asset, no mssql asset. But after I install MBC(message-based collector),esmmssqltpi.exe. And regist agent with sa user of SQL Server. After import agent and asset I found the SQL server asset. 

   I choose Security Essentials for Microsoft SQL Server 2008 standard to collect data. It asking the credentail of SQL. !!!!

   Normally, agent-based should not ask the credentail, it should be the agent-less collector. Please guide me about this idea.

Thanks you
