Wt

Hi,

has anybody an idea how to implement login with native Unix user, password?

I thought it would look something like this:

• Derive own class from Auth::AbstractUserDatabase
• Replace UserDatabase dbo class in hangman example
• Reimplement some methods like identity etc. with access over Unix pam API.
• done

I'm failed at the second step... :((((

I have written my own UserDatabase class derived from Auth::AbstractUserDatabase and configured my webpage so as in the hangman example but without dbo things. All methods return invalid user object for test purposes.

Wt-Application was crashed after click on login button. Crash happens in method Wt::Auth::AuthModel::validate()

Can anybody help me?

//Constructor content of WApplication class

   session.login().changed().connect(this, &ProdMon::loginChanged);
   Auth::AuthModel *authModel = new Auth::AuthModel(Session::auth(),
                              session.users(), this);
   authModel->addPasswordAuth(&Session::passwordAuth());

   Auth::AuthWidget *authWidget = new Auth::AuthWidget(session.login());
   authWidget->setModel(authModel);
   root()->addWidget(authWidget);
