login fails after clickonce deployment

   Hello, I have an aplication that locally runs ok, when I publish to use clickonce it seems to work but I get an error when login  in that says it cannot cast  System.Security.Principal.GenericIdentity' to
the type 'Model.AppIdentity'
On this method

private void SetLoggedInUser(PersistenceManager pManager,
IdeaBlade.Persistence.SessionBundle
pSessionBundle)

{

      AppIdentity identity = (AppIdentity)pSessionBundle.Principal.Identity;

      .

      .

      .

}

Where AppIdentity is an implementation of IIdentity adding 2 values. This cast works ok when running locally on the development machine, but if I publish I get that error. (Security is enabled for ClickOnce as a fully trusted application)
Is there any other configuration needed? 
Thank you
Diego
