WCF RIA Services Authorization

Question

Hi guys,

Assume we have two groups "Admins" and "Users". Admins are able to use any operation available in the service but the users can only use some of them.

Should I add the "Admins" group to every single operation or if I just write it on top of the class will do the trick?

Thanks.

Multiple RequiresRole attributes are combined with an AND while multiple roles passed to a single attribute are OR'd. In your case, you'll want to OR the attributes ("User" or "Admin") so you'll have to apply "Admin" to every single method.

// "Admin" && "User", equivalent to using a class attribute for "Admin"

[RequiresRole("Admin"), RequiresRole("User")]

// "Admin" || "User"

[RequiresRole("Admin", "User")]
