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.

I want my OpenBSD 6.4 services to authenticate users from a remote LDAP server ; namely a Synology Directory Server (DSM 6.2.x). It turns out that this a standard OpenLDAP 2.4.x configured to accept replication refreshAndPersist mode. So let’s configure a Master / Slave Replication system between Synology and OpenBSD.

I wanted to share users authentication and permissions between the QNAP TS-453mini and my OpenBSD servers. An option is to enable and manage LDAP server on the QNAP and configure OpenBSD 6.0 to authenticate the users on the remote LDAP service.

Like I did with NetBSD, this is how to build an almost complete Mail Server with OpenBSD.
We’re gonna use a Dovecot IMAP server and a Postfix SMTP server. Postfix will use Dovecot as a SASL service. Both will use LDAP to identify valid users and e-mail aliases. Mail sanitization will be provided by RBL, from Postfix, and by the
spamd shipped with OpenBSD.

Those are the directions I used to setup an almost complete OpenSource Mail server running NetBSD and pkgsrc.
The Mail server will feature:
- E-mail exchange (MX) role on the Internet;
- E-mail gateway (SMTP) for internal LAN users ;
- E-mail access (IMAP) for internal LAN users ;
- Secured (TLS and SASL) access for internal users;
- Greylisting, RFC check and RBL mail filtering ;
- Directory (LDAP) for e-mail entries ;
