Restrict Access in WCF using FormsAuthenticationTi

Question

I've seen solutions where you can restrict access in WCF using the membership in asp.net.(How do I restrict access to some methods in WCF?) But i'm wondering if there is anything similar using the FormsAuthenticationTicket.

I don't have the Membership configured on my site, and i'm using the FormsAuthenticationTicket and methods in WCF to log in and so on.

The WCF-Service is not configured to use SSL YET, because the man i work for have not bought a cert trough our hosting company(don't know if relevant)

The main thing is that i need to protect my some methods in my WCF-Service from unauthorized access, and if theres another simpler solution i would love some input on that to.

I'm very new to WCF and security overall, but familiar in ASP.NET and C#. I would love for some pedagogical answers, and not just a solution or ideá

UPDATE: Some pastebin links for my solution:

Answer 1

This is possible and is commonly used - you have to guard your calls with the principal permission requirement.

Here is one of tutorials by myself

Don't let the title mislead you, this is not not only about Silverlight but any other way of accessing the WCF service that is capable of carrying cookies.
