Custom WebService + FBA = 0x80070005 (E_ACCESSDENIED

Question

I've created custom web service in Sharepoint 2010, and custom FBA. I try to connect from a Win Forms app on another computer.

1/ I log into with cookie container (Authentication.Login)

2/ I call the custom web service with same cookie container

In the web service, SPUser myUser = SPContext.Current.Web.CurrentUser; is ok. But every other operation throw Access Denied error... :

'SPContext.Current.Web.AllowAnonymousAccess' a levé une exception de type 'System.UnauthorizedAccessException'

I get this even if my user is granted for full access.

What can be wrong?

Edit: same problem when I call standard Web Service, like Lists.GetList(name).

Answer 1

I made a clean install and everything is ok now.
