[FIXED] Spring security LDAP WebSecurityConfigurerAdapter deprecated

Issue

Since WebSecurityConfigurerAdapter was deprecated in 5.7 I've got a question how to replace old config

Old config:

public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {

    auth.ldapAuthentication()
        .userSearchFilter(usersFilter)
            .contextSource()
            .url(url)
            .managerDn("login")
            .managerPassword("password");
    }                                                                       
}

In spring.io not said how to replace .url(), .managerDn() and .managerPassword()

Solution

@Bean
public DefaultSpringSecurityContextSource defaultSpringSecurityContextSource() {

    var contextSourceFromProviderUrl = new DefaultSpringSecurityContextSource(url);
    contextSourceFromProviderUrl.setUserDn("login");
    contextSourceFromProviderUrl.setPassword("password");

    return contextSourceFromProviderUrl;
}

@Bean
AuthenticationManager ldapAuthenticationManager(BaseLdapPathContextSource defaultSpringSecurityContextSource) {

    var factory = new LdapBindAuthenticationManagerFactory(defaultSpringSecurityContextSource);
    factory.setUserSearchFilter(usersFilter);

    return factory.createAuthenticationManager();
}
