Bloomreach Login via saml , SecurityContextHolder is null

Hello everyone,
I try to implement SSO for brxm (14.7.11). I implemented it according the spring tutorial.
my filterChain looks like this:

  http
                .authenticationProvider(samlAuthenticationProvider(samlUserDetailsServiceImpl))

        http
                .httpBasic()
                .authenticationEntryPoint(samlEntryPoint());

        http
                .addFilterBefore(metadataGeneratorFilter(), ChannelProcessingFilter::class.java)
                .addFilterAfter(LoginSuccessFilter(), AuthorizationFilter::class.java)

                      http
                .csrf()
                .disable()
                .authorizeHttpRequests()
                .requestMatchers("/saml*", "/*.gif", "/*.jpg", "/*.jpeg", "/*.png", "/*.jsp", "/*.js", "/*.css", "/console*").permitAll().anyRequest().authenticated()

        return http.build()

after logging in, it is jumping in the doFilter method of the LoginSuccessFilter and there I try to get the authentication status from SecurityContextHolder, but it is null. What do I miss in the configuration?
And how can I connect the user details to the HippoUserManager?
Thanks a lot for your help in advance!

Hi Henriette, you can find some documentation around SAML integrations here: Shibboleth/SAML SSO Integration - Bloomreach Experience Manager (PaaS/Self-Hosted) - The Fast and Flexible Headless CMS

If your SecurityContextHolder is null, it’s likely that the Spring Context was not initialized properly. Do you have any error logs that you can share?
