WebService access permissions

[Gilad Kapelushnik]

Hello I have a webservice exposing various methods. I also have a win application (Click-once) that uses the webservice methods. I would like to prevent any other access to the webservice so no other user\client can invoke the methods. I do not want to manualy check this on the server side but would more like to have a strong name signing between the webservice and the windows application. Any one can help on this ? Gilad.

you can use another web service and web methods for authentication. now anytime anyone use your web methods you can check authentication.

Hi This is my second option. I wouldn't want users that *DO* have authorazation to use the WebService to use it without the specific application that I give them. I want the users to be able to use the webservice ONLY with the special application I provide. Gilad.
