Hello everyone,

I am very new to WCF. I am having a difficulty with wcf. I need to implement Single Sign-on. I am performing authentication with SqlMembership. For SSO, I am suggested to use WCF Authentication service and Role Provider with Membership. I searched a lot but I cant find any way to consume this authentication service. how can we set our role provider and membership provider to a wcf service? how can we perform SSO with WCF? I have found so many link that shows how to enable Authentication service but none for consuming them. And Role provider is quite new to me.

I need your guidance geeks.

It will be more helpful If i will have example or link to syntax.
