This webservice is written in C#, and I want to use an OpenID to authenticate.
This authentication request will be called by a WPF, and an asp.net applicantion. the webservice will then try to authenticate in OpenID server, and in this case I use OpenID-LDAP software.
The big problem is how to use OpenID without showing the web page to login (the webservice is who is going to inform user and password)?
