Description
- Spring boot version: 2.7.1
- JDK version: 1.11
I'm moving from old authentication style to the new authentication style based on the article published in the blog spring-security-without-the-websecurityconfigureradapter -> before adding the issue I have looking in stackoverflow for similar issue, here in closed issues, dead loops etc... but I have not been able to find anything in the same direction.
Everythings goes fine, except when I introduce bad credentials, then the application seems go into a loop until it is raised an java.lang.StackOverflowError: null ( here the full error stack trace ) error.txt
I have created a sample code at https://github.com/darkman97i/spring-security-test ( in the sample I'm using two providers in memory and jdbc. Also I included h2 database with users credentials into for a quick test ).
Thanks for your time

Your use of the shared authentication manager builder results in a provider manager that is using itself as a parent. This results in an infinite loop as when the login fails, the provider manager queries its parent to see if it can authenticate.
This problem isn't directly related to Spring Boot as it's a Spring Security usage question. Your sample works if I inject an ObjectPostProcessor and create a new AuthenticationManagerBuilder:
@Bean
public AuthenticationManager authenticationManager(HttpSecurity http, ObjectPostProcessor<Object> objectPostProcessor) throws Exception {
AuthenticationManagerBuilder authenticationManagerBuilder = new AuthenticationManagerBuilder(objectPostProcessor);
However, I'm not sure if this is the best way to solve the problem. Unfortunately, there are no hits on AuthenticationManagerBuilder in the Spring Security reference documentation so it doesn't appear to offer any guidance.
Can you please open a Spring Security issue that references this issue, and comment here with a link to it? That will bring the problem to the Security team's attention. They could perhaps prohibit a cycle among the ProviderManager ancestors, make some updates to the documentation, or something else that they feel is more appropriate.

@wilkinsona First, sorry for my late answer. The issue opened at spring-security is still open but the spring-security team suggested me another direction and it worked perfectly. I share complete solution it worked for me, maybe help other users.
Thanks a lot for your help and time invested with us, for me, can close the issue.
