Can someone point me to a [relatively] simple walk-through on how to properly configure an ASP.Net hosted WCF 4.0 service to impersonate the credentials of a caller for just certain methods of the service, but allow anonymous access to other methods?
I've been reading a lot about this on MSDN, but the more I read, the more confused I get. Maybe I'm just a dunce, but this seems a lot harder than it should be :-(
I have looked through the posts here on SE, but none seem to point to an end-to-end sample or tutorial. There is a WCF guidance document on CodePlex, but it seems hopelessly out of date, and hasn't been updated since 2008.
Any help here would be GREATLY appreciated.
