Ldap over SSL issue in native image

[kartik-kaushik]

Describe the bug
Spring Boot 3 native image not working with spring-ldap over ssl

Sample
Via the Spring Initializer, create any project with:

spring-boot-starter-parent:3.0.2
spring-boot-starter-data-ldap
spring-boot-starter-actuator

Application.properties
spring.ldap.urls=ldaps://localhost:636
spring.ldap.base=ou=people,dc=admin,dc=com
spring.ldap.username=cn=admin,ou=service_accounts,dc=com
spring.ldap.password=password
management.endpoint.health.show-details=always
management.endpoints.web.exposure.include=*

Check with actuator health endpoint. The application works normally, but with native image giving error:

Kindly help in resolution of the same. If not supported, is there any alternative or work around for now?

@jzheaux Any update on it or tentative date or workaround?

[jzheaux]

This appears to be a duplicate of #723. Have you already tried the workaround there?

I'm closing this due to lack of activity. If there is more to discuss, we can re-open at that time.
