AX 2009 - VS2010 C# - Business Connector - I'm writing transaction directly

Please,

Can any body help me, I have a webservice developed with VS2010 C# interacting with Business connector with Dynamics AX 2009, and is functionally is working with no problem.

But I see, that with the AX user that use to connect with the "LogonAs" with Business Connector, doesn't have any restrictions with the definition of "AX USER GROUPS", even if I put the AX user with NO AX USER GROUPS.

¿How can I restrict the with the USER GROUPS the Business Connector USER?

Sorry with me English, I am from Chile, and speak spanish

I hope someone can help me.

Thanks
