WebSecurityConfigurerAdapter: Unable to use custom AuthenticationEventPublisher #7515
Description
Summary
When using WebSecurityConfigurerAdapter there currently seems to be no way to configure a custom event publisher.
Actual Behavior
WebSecurityConfigurerAdapter::getHttp currently always creates a new AuthenticationEventPublisher and overwrites the one set for the AuthenticationManager. There does not seem to be a way to modify that.
Expected Behavior
A custom event publisher set via configure(AuthenticationManagerBuilder) or similar should be honoured.
