I have just discovered some issues with my previous article on OpenLDAP replication between Synology DSM and OpenBSD OpenLDAP. In the end, it is not possible to log-in on the OpenBSD LDAP instance using the original userPassword. Short story: CRYPT seem to not be various-platform-compatible.

Complete (almost) Mail Server with NetBSD
