I have one application(Application1) which is SSO enabled and in that URL there is one parameter passed by user which is used along with userid and password for authentication.
For ex: Andrew works in Project department, and there are lot of other departments also. To login into the application he will type URL first as: http://myapp.com/project and then this login page will ask for userid and password. To authenticate Andrew all 3 things are taken into consideration. Userid, password, and department(passed in URL).
Now I am creating another application (Application2) which has spring security. So for authentication purpose I need to go to my Application1 and pass the department from Application2 in the URL. Once the user is authenticated I need to come back in Application2.
I am able to redirect to Application1 from Application2 by using .formLogin().loginPage() but have no clue in passing the department to URL runtime and come back to Application2 after authentication.
Please help me here.

I have a difficulty in understanding Spring Security and any tutorial I found was not tailored to my needs. So maybe I'll explain what I think and what I want to accomplish.
I want to create a website with Kotlin/Java backend and frontend in React. This website would need to have users with different roles (user, admin).
And (I think) the thing I need is some kind of backend that has 2 endpoints:
register (to create users in database)
login (to, based on username and password, fetch user info and role) - as some kind of token? This returned token would be then used by frontend to display specific options (i.e. do not display "ban user" for regular users) and it also would be sent to backend for checking if the person who requests for specific endpoint really should be able to call this endpoint (i.e. it should be forbidden for regular users to use "ban user" endpoint)
What should I read about, what keywords should I look into to achieve this?
For purely the Spring Boot part of the implementation, the following should do
(/register) Signup/Register endpoint taking all required parameters for your business logic. e.g Username , Password , Full Name as well the roles
(/login) For logging in , you need a token forwarded to the front end, which will then use this token in the header for the session. JWT tokens seems like what you need(sample below). For the other part of your requirement, you can keep the user object (with roles) in the session as well as check user role on the backend in the "ban user" endpoint and process accordingly.
JWT Authentication with Spring Boot
I found a good starting point in the following sample

Before adding, yes it works when I give the entire url like http://localhost:8080/onedrive/oauth2/success/1 in the list of uri in azure uris. I am using code flow to authroize these tokens.
But as per the docs, it should work with me just mentioning the domain name there, like http://localhost:8080. Which it doesn't.
I want to do something like send the user id along with every request for me to keep track of which user I should link this accees token to, and have no idea to do so, if this issue is there. My current application logic is, when my application sends the user details and calls my spring API, I want to handle all these transfer of tokens in the server side, so I want to transfer this userId as my path variable. How do I go about doing this? Has anyone done this, can they explain to me any other different solution?
You can't add custom details to OAuth redirects and it is best practice to always register the full redirect uri.
In terms of tracking the user, after login the token has a user id and you can also get fields such as user name and email - so both the UI and API will know which user each token is for. I can provide further details on mechanics if needed.
The user id in a token is often a generated value, whereas the user id you want to use in API path segments is maybe a user id from your app's back end database - if so you will need to map between token details and database details.
If you provide redirect uri as http://localhost:8080/ then it means you are handling the api response in
/
endpoint and not
/onedrive/oauth2/success/1
To get to know the user to whom you are linking, few ideas which you can use are
1) Use security to obtain the logged in user credentials (Ex: Principal if you're using Spring security in java)
2) After successful authentication, use the user id you have and send one more request to backend and store it database with userid as a key
I have a requirement that needs to have login page at the service provider and I use java web app. Is there any way to use the spring SAML libraries to achieve this behaviour ? If so, what could be the steps? (it seems the default behavior of spring library is to redirect to IDP login page and I am not sure if we can configure to host login page on the service provider and relay that request to IDP)
I think what you're looking for is having two different ways to authenticate, one locally and one through SAML. I believe for having a login form, you would want to separate configurations with different AuthenticationEntryPoints, i.e. go to /login for local or /saml/login/alias/" + spAlias+ "?idp=" + spEntityID for direct login to SAML.
It sounds like right now you have SAML protecting any URL, which by default redirects you to the IDP since it's configured. The first step that I would take is getting user name and password authentication working with logins independently of SAML, then add SAML back in. Be sure to list whatever URL the login form uses as permit all so SAML doesn't kick in.
I have an application and API. I am using Spring and Spring security for both. Authentication is required to access API.
I configured RESTFUL web service only respond when authentication is successful (handling with JSESSIONID after login) which makes querying database not possible if user is not logged in or credentials are wrong. But somehow, I need to access database and make some changes for forgotten password. I need to check if requested email is on the record. Also, update the database after password change. eg; If I make 'UPDATE USER' action permitAll(), there will be a security problem.
Can you give me some ideas to handle that problem?
You can create some user with permissions to change password and later when changing password automaticly login this user -> send request ->logout user and all of that behind user view.
I'm a newb to spring security and I'm not sure where to start. I have requirements to have a multi-page authentication. The first page authenticates the username, if the username exists the web app progresses to the password page. (site image) The second page authenticates the password, if successful then the user is authenticated. I'm not sure how to fit this into spring auth. Do I add multiple login-filters and authenticationproviders ? If I add multiple authenticationproviders, will I be authenticated after the first login ?
Page 1: User enters username. Submit this to your own controller where you check if the user exists. If the user exists, display page 2, pass the username in the model. You better not include Spring Security authentication in this step.
Page 2: User enters password. Use a readonly or hidden field to keep track of the username. Submit the form to Spring Security form login filter. You don't need multiple authentication providers.
Note: This approach has an information "leak"; any visitor can check whether a username exists in the system or not.
It depends on the kind of your authentication:
JDBCAuthentication
You can do with #holmis83 suggests.
LDAPAuthentication:
I am afraid tht you can't do that.
