i have one issue, i am using cookieSession for passport-saml. i get the logout working but i have configured timeout, i get an error after timeout when user is trying to logout.

_

TypeError: Cannot read property 'nameIDFormat' of undefined.

_

TimeOut configuration:

app.use(cookieSession({ name: 'session', keys: ['keyHS'], maxAge: 10000 })); app.use(passport.initialize()); app.use(passport.session());

samlStrategy.logout(req, function(){
               req.logout();
               res.redirect('/');
           });

What should i do here to redirect the user to login page after timeout.

I just took over maintenance of this library in May, and I'm afraid I haven't gotten much into the logout functionality yet, but I'm happy to work with you on figuring it out.

Have you tried setting the logoutUrl option? I don't think it's documented, but you can see the implementation at saml.js:218.

You may also want to write out the contents of the logoutRequest being generated in saml.js:generateLogoutResponse() to make sure that looks appropriate.

Check out pull request #72 for a fix for the current implementation. You need a logoutUrl as well as entryPoint.

To actually get it to work on the IdP, you have to generate a logout request like

var samlStrategy = passport._strategy('saml');

samlStrategy.logout(req, function(err, requestUrl) {
    // LOCAL logout
    req.logout();
    // redirect to the IdP with the encrypted SAML logout request
    res.redirect(requestUrl);
});

You'd also need to have a callback from the IdP set up so they can redirect back to your site (wherever you want to have them go). Alternatively, you can have a generic exports.signout function that only does local logout and redirects to the homepage, and use a custom exports.samlSignout function that takes care of only the samlStrategy.logout call.

I have this working in a local app based on my fork in the Pull Request above. Good luck!
