Im currently working on a nodejs project and require some authentication. As it stands I just use expresses basicAuth function, however I can't seem to figure out how to do more advanced operations. For example I have two url parameters say bob and steve. If the user navigates to website.com/bob I want it to ask for username:"user" and password:"password". However if the user navigates to website.com/steve I want it to ask for username:"user2" and password:"password123"
Would this be possible using basicAuth and if so how? Or would something like passportjs be able to accomplish this task? I dont need an amazing solution just something to stop people accessing certain areas.
What you are trying to achieve is probably access control and I suggest you use a access control list module which will allow you to implement policies as to which users/groups have access to which resources within your application.
This way, even if a user provides their username/password pair, they will not be allowed to access that resource based on the policy which is a better option application design wise.
For a start:

How would I go about deploying a web app intended for only a single user (myself)? I feel like making a login that only accepts 1 user is the wrong method and also easy to hack? Would it be a good idea to make it only accessible from a certain IP? Please advise! Thank you. Backend will be using nodejs.
If I were you, I would program the back-end the proper way. This involves generalizing the entire implementation so that any hypothetical user with the correct password could use your login system. You could still authorize and authenticate the application so that when anybody else tries to log in, you automatically decline their request. If you are concerned about security, ensure that you are using SSL, basic encryption, hash passwords and, most importantly, do not use your own authorization library. It is far more secure if you use OAuth instead of using an IP, for example. Last, but definitely not least, make it as hard as you can for hackers to steal your data in the client side. This way, you also learn a lot of things that might come in handy in the near future.
Help! I have no clue what I am doing here. I am reworking old C# code and I need to use LDAP for integrated authentication on an intranet. The user should be completely unaware of this process but what I need is to have the React page contact the express server passing in the users domain id. From there I need to perform basic authentication then return all the groups that this user is a member of for validation.
I have read numerous tutorials on passport-activediretory and passport-ldap and so on but I am still confused.
What I am looking for is a single function that will run on every call to the API and will return either validation or, if requested, validation and group names the user belongs to.
What is available to make this process very simple. I looked at passport but to be honest authentication is not my milieu so I am at best uncertain as to how any of it works.
I am hoping that it will be as simple as app.all("*", functionHere());
Being very new to node (first project) I really need extensive help, hopefully in small words.
Thanks
For now I have switched to a .Net back end which support for LDAP integration without the need to a lot of excess code.
Will move back to Node once the application is finished then port it over.
I was trying to find it in docs or anywhere on the web but I did not find.
What I am asking about?
I am building website for multiple users. Frontend is not important, back backend API is being build in Loopback.
Every user will be assigned to some, let's name it GROUP.
Group content will be then exposed on subdomain but it is not important now.
Users will be kind of admins of their group.
I will have plenty of different models, but I will always have to protect user from accessing elements which not belongs to his group.
How should I do it? I think it will be some middleware but I do not know how to do it properly.
Of course, every user and every element have field "group_id".
I am also trying to find a good solution... I did find this npm package that looks worth a try: https://www.npmjs.com/package/loopback-component-access-groups
Here is a short description of what the package is used for:
"This loopback component enables you to add multi-tenant style access controls to a loopback application. It enables you to restrict access to model data based on a user's roles within a specific context."
I'm struggeling with the same problem, and I did not yet find a satisfatory response.
My workaround is explained in this question. I've got my user ID and with this, I retrieve the data I need to restrict the access. Then I alter the query in accordance with fetched data.
Context: I have never work with Stormpath before and want to fully learn how to do certain stuff. To practice I'm creating my own portfolio, including the CMS.
My question is, how can I restrict the registration of accounts to a handful of specific emails using Google API (only me should be able to add and remove content from my own portfolio).
E.g. Allow ONLY example1#gmail.com and example2#gmail.com to register.
I could do it manually, but I do not want to do that. Steps I would like to follow are:
Specify emails
User tries to access the CMS
User is prompted to login or register
Only if user is in the specified list of emails, user can register using Google's API.
I do understand this is a very general question that involves several fields: Google's API, Stormpath, not to mention Express and Node, but maybe someone else solved this problem and I can see some code. Thanks.
I'm the author of the express-stormpath library which I'm assuming you're using. There's nothing out-of-the-box that does this, so I'd like to point out the best way to do this:
Create a custom registration route, and model it after the built-in stuff here: https://github.com/stormpath/stormpath-express/blob/master/lib/controllers.js#L143
In your custom registration route code, add in some code that checks to see if the email address supplied by the user is a valid one or not.
If not, reject their request.
Now, in the real world you probably wouldn't want to do this sort of thing (it's a lot of extra work, and doesn't buy you much). What you'd probably want to do instead is: completely disable account registration on your website. This way, only YOU can create an account using the Stormpath dashboard on https://stormpath.com, but login still works on your site so that you can log in.
Does that make sense?
So basically, what I'm suggesting is that you disable registration on your site by saying:
app.use(stormpath.init(app, {
enableRegistration: false, // this will disable the registration page / functionality
// ...
}));
Hopefully this helps =)
Im using GWT, GAE to make a web app.
I looked at a bunch of tutorials regarding implementing a login system but most of those tutorials implement it so it's mandatory to login to access the web app. How would I go about making it so that anyone can access the app but if they want to use account specific functionality, they they have the option of signing up for an account.
There are two parts to it.
First, in your client code you check if a user is logged in. If so, you allow access to the "closed" parts of the app. If not, you show a link/button to login and hide tabs/views that are accessible to authorized users.
Second, in your server code you specify which requests do not require authentication and which do require it. This is necessary if a user somehow figures out how to send a request without using your client code.
For example, in my code some requests have checkSession() called at the very beginning. If no authentication object is found for this user in session, this method throws LoginException to the client. If the authentication object is present, the request continues to execute normally and returns requested data to the client.
Further to Andrei's answer, if you want a framework to manage the sessions for you, you can use GWT-Platform, which has an excellent Gatekeeper feature.
I use it for mine and I have a LoggedInGatekeeper class. Simply add #UseGatekeeper(LoggedInGatekeeper.class) to the constructor of each presenter proxy and it checks if the user is logged in. If you want anyone to be able to access that page simply annotate with #NoGatekeeper. Easy!
It takes a bit of setting up but it's a great MVP framework. There are maven archetypes and samples etc.
Hope this helps.
