This has to be done a little differently with our extensions. Advanced page access rules are only available in Databridge, but I see you don't own that product.
The easiest solution (if you don't own DataBridge) is to save the same session variables that Dreamweaver login uses so that you can use the old restrict access server behavior based on user group.
MM_Username and MM_UserGroup
You can add those variable names to the list of saved columns in your login (it doesn't matter which column you use for MM_Username, but save the access group column as MM_UserGroup).
Then you can just use the Adobe Restrict Access to Page server behavior to do access group based page access.
