Some questions:
How will affect this decision, the SOGo integration in NS?
It’s too early to put this question?
Let’s say that NS will not support SOGo anymore.
Will remain WebTop 4 and Roundcube.
WebTop 4 can be integrated with Samba AD but has some lack regarding Active Sync (“Active Sync protocol is supported only on Android and iOS devices. Outlook is not supported. Mail synchronization is currently not supported.”).
Roundcube can be integrated with Samba AD ?
I will learn more about the two “email clients/groupware”.
Because of WebTop 4 integration in NS, I think will be the first.
A lot of articles here, about WebTop.
