When running SimpleSAMLphp in proxy mode with hosted IdP's on the same domain, the proxy will not be able to resolve the auth token cookie set by one of the hosted IdP's on a different subdomain.

I have created a patch for this in the method below, that I can create a pull request for if the issue is accepted. Lines to in ada.

The text was updated successfully, but these errors were encountered:. Hi renklaf! I'm not sure I'm following. The remember me mechanism has nothing to do with the auth token cookie. The former allows the IdP to keep track of the user so that the username is pre-filled, while the latter is an anti-session-fixation mechanism. Hi jaimeperez. The remember-me-mechanism does in a way impact the auth token cookie.

If you take a look at the following:. The user up being redirected to frontpage that returns and error due to not being logged in as admin. Hi again renklaf! To be honest, I've always thought the remember me mechanism was flawed from the beginning, and should have never been included in SimpleSAMLphp as is.

It lacks proper documentation and it's not really usable in large-scale deployments.

Would you mind opening a PR with the fix? Also, I think we could easily reduce it to a one-liner:. Note that proper cookie parameters should be used for both the SimpleSAMLphp session cookie and the auth token. I'll open a PR today. You are absolutely right, I didn't notice that that setCookie method was coming from different classes when setting each cookie.

That should work, I think. Fixed in We will be writing an Angular 2 app that uses JWT for authentication. Grab the Github repo if you would like to follow along. Our last article comparing cookie to token authentication was over two years ago.

Since then, we've written extensively on how to integrate token authentication across many different languages and frameworks. The rise of single page applications SPAs and decoupling of the front-end from the back-end is in full force.

Frameworks like AngularReactand Vue allow developers to build bigger, better, and more performant single page applications than ever before.

Token-based authentication goes hand in hand with these frameworks. Before we dive further, let's quickly recap how these two authentication systems work. If you are already familiar with how cookie and token authentication works, feel free to skip this section, otherwise read on for an in-depth overview.

This diagram is a great introduction and simplified overview of the difference between cookie and token approaches to authentication. Cookie-based authentication has been the default, tried-and-true method for handling user authentication for a long time. Cookie-based authentication is stateful. This means that an authentication record or session must be kept both server and client-side. The server needs to keep track of active sessions in a database, while on the front-end a cookie is created that holds a session identifier, thus the name cookie based authentication.

Let's look at the flow of traditional cookie-based authentication:. While there are different ways to implement tokens, JWTs have become the de-facto standard. With this context in mind, the rest of the article will use tokens and JWTs interchangeably. Token-based authentication is stateless. The server does not keep a record of which users are logged in or which JWTs have been issued.

Instead, every request to the server is accompanied by a token which the server uses to verify the authenticity of the request.These tokens are used for example by the selfregister module, both when creating new accounts and when resetting an existing password.

The tokens are sent via email as part of a URL, so that the user in possession of the token is granted access. This is a fairly common mechanism. A security issue has been found in the way these time-limited tokens are created, allowing for malicious manipulation so that a token's validity period can be indefinitely extended.

Tokens are built by prepending a time offset to the token itself, so that this offset can be subtracted from the current time and get the original time slot when the token was created. While the time slot, the salt used and the verification data if any are authenticated using a hash function, the offset prepended to the token lacks any kind of authentication.

This means an attacker who manages to get an expired token by some means will be able to make the token valid again by increasing the prepended offset as much as needed to force the validation routine to hit the original time slot when the token was created on. In other words, tokens created like this are not bound to the current time at all. In order to fix it, the offset itself is added to the hash computation, so that a change in the offset produces a new hash that won't match, and therefore the token will be considered invalid.

Attackers who manage to get access to expired, secret tokens, may be able to modify them to make them valid again and use them to impersonate legitimate users.Many SPAs and Next. Unfortunately localStorage and simple cookies aren't the safest place to keep sensitive data because both can be accessed from third-party scripts and browser extensions.

HTTP-only cookies can't be accessed from client-side JavaScript, so third-party scripts and browser extensions won't even know they exist.

You can identify them by looking for the httponly attribute in the set-cookie header of an HTTP response:. By existing on the same domain as our Next. Thanks to Next.
