The user management capabilities are not reflected in the capabilities API. That is, they do not show up in the information returned by the FdoIConnection object's GetCommandCapabilities method. You can use the FdoUserManager object's SupportsDatastoreGrants and SupportsWindowsAuthentication to control the execution of some of the object's methods. For the rest of the object's methods you must test for the name of the provider to determine whether or not you can call the method.
