Speaking about multiple DB ...
A my customer has a server (CentOS 6.x, dovecot 2.0.x, postfix, Squirrel+RoundCube with vacation and password plug-in), with about 3.000 users (about 200 different domains), all defined as system users and home as /home/mail/%user%
The system works fine. Its only additional interest is authenticating users like u...@domain.tld / password (maintaining also the current user.domain / password).
Is it possible and How complex configuring a similar environment? Only matter of sync /etc/shadow and DB or other problems? Regards, Paolo
