Hi how do I implement OAuth 2.0 for Microsoft exchange in spring boot application

The springboot application uses camel configuration and I want to implement OAuth 2.0 for connecting to mailbox of different application through Microsoft exchang using IMAPS protocol. How do I implement it.
I have the tenant id, client id, token value and token id.
We added a component specific for that: https://camel.apache.org/components/3.20.x/others/mail-microsoft-oauth.html

Accessing keycloak endpoints in a spring boot cloud service

In an existing system, that is a spring boot cloud gateway I'm trying to switch out the code that generates the jwt tokens and manages users for Keycloak.
I found the rest endpoints via this link https://www.baeldung.com/postman-keycloak-endpoints. And that all works fine.
The problem is I can't find for the life of mine if Keycloak has a client for that in their managed code? Or do I need to write a custom client for this?
I can't really use the spring boot adapter because of the complexity of the already existing system.
Kind Regards,

How to create custom login module in spring boot web app using spring security

I’m trying to build a spring boot web app where I have my own login module with rest api backends that would do credential validation for me. I need to use spring security to have TLS implemented but even though I managed to override the login page the css would not work. And secondly,when I give the loginprocessingurl in the securityConfig as my controller route to what manages the credential validation, it says too many redirects.
Can I bypass the login module entirely ?
I don’t want to encrypt the password at client end and would really like to utilise spring security.
Thanks in advance!

Spring Azure AD Authentication

I'm trying to implement Authentication with Spring Security via Azure AD to my Spring Boot Application. The Azure AD Portal is not availible to me and managed by others.
How can I perform an easy Authentication using the Microsoft login of the company to verify that the user exists in the Azure? I just need to know in the application if the user was able to perform the login.
Thanks :)

AFAIK, Without having Azure portal its not possible to use authentication with Azure AD for your application. It requires app registration details such as client id, Tenant Id, redirect uri etc.
We can not able to do such operation if are not having account on Azure . And Azure Active directory has a high level security so that you can not get to know whether this user is from Azure.
For more information please refer the below links:-

Spring security single sign on

I'm using Spring-Boot and annotation based Spring-Security and I would like to use another site as one of my authentication providers.
I search on google but not getting any proper example or related solutions.
Let me know how can I implement Single sign on for 2 different application.
Please Guide.
Thank You.
You could use Jasig CAS to implement SSO and it is supported by Spring Security: https://docs.spring.io/spring-security/site/docs/3.0.x/reference/cas.html
You can use #EnableOAuth2Sso on your spring-boot application set some properties: client id, client secret, token endpoint for your oauth2 server, etc.
This tutorial is for an angularJS client on spring-boot but the server side is similar: https://spring.io/blog/2015/02/03/sso-with-oauth2-angular-js-and-spring-security-part-v
