We want to use local sonar build-in users database and additionally ldap. At the moment only either or works.
E.g for the sionar pdf report plugin you need an sonar user account, because the plugin uses api which need authentification. Here we want to use a local sonar account and not need to create ldap account for it.
Secondly we need a local "backup" user account for an ldap account, in case ldap fails, and without having to change the sonar.authenticator.class
Maybe the ldap Plugin can support to have several sonar.authenticator.class, e.g
sonar.authenticator.class: org.sonar.plugins.ldap.LdapAuthenticator, org.sonar.EmbeddedAuthenticator
