Currently I have a e-mail solution with a LDAP server and a IMAP server. I have about 200 clients connected to this solution.
I would like to have a calender service aswell, and as far as I know, zimbra is able to provide that!

However, I would like to keep using my own LDAP and my own IMAP server!

I've tried configuring Zimbra to use my own LDAP server - and when testing a username and password - it seems to work fine!

Is it possible to connect Zimbra to my own LDAP server(which seems to work) and my own IMAP server - and then just use Zimbra for calendar!
