Hi! We are implementing system that will be used for educational purposes. It consists of: Samba4 as AD DC and fileshare; dhcpd; moodle; postfix; RADIUS and some other services. We want to use common user database as authentication backend for all of these services. So we see two possible solutions: 1. Use LDB as authentication backend and configure all services to work with it. So we need to extend LDB' schema, can you give some advice about possibile solutions? Which services are supported by LDB and is this support permanent or not? 2. Use LDB as authentication backend only for Samba4 and LDAP as authentication backend with another services. In this case we'll need to organize merging users from LDAP to LDB. Are there some solutions for synchronization? Which of those is better? Is there any web interface for working with LDB's database? (for adding users, editing user information) Thank you. -- Regards, Andrii Melnyk NTUU "KPI", FICT, ACTS System Administrator
