Deply IIS 8 Site to IIS 7

In IIS 8 I packaged a Web Site using the appHostConfig  provider.

When I try to import this site into IIS 7 I get the error message:

Child object 'customAuthorization' cannot be added to object 'security'. The 'security' provider may not support this deployment.

 Is there a workaround for this?

Thanks
