@J. A. Calvo
Thanks for the News.
I'm developing a project and look for a AD/LDAP-based user-management with Mail and Exchange functionality (and others, which Zentyal delivers out of the box) as core for other (dockeriezed) services, which will authenticate against it.
at the time of being, it hast not to be "very" stable, since the project is in a the phase of "proof of concept"
the used AD/LDAP-server should be able to run in an LXC/LXD container.
The Zentyal Server 5.0 (based on Ubuntu Server 16.04 LTS) will be released in October-November.
Is there a possibility to get an dev. snapshot/beta of 5.0?
TIA
