I'm currently in the proces of evaluating Zimbra; Looking really good so far
One thing i noticed tough is that Zimbra comes with its own customized version of OpenLDAP. I would like to use my current OpenLDAP installation instead of the one that comes with Zimbra.
Using the external authentication options is not really a good substitute for me since that would require syncing additional info like given name, adres, etc.
From what I saw the only thing that Zimbra expects from its LDAP server is a cn=Zimbra tree, Zimbra schema's and a custom slapd.conf with indexes and ACL's.
Is there something im missing ? Or could this kind of setup be used in a production environment ? Or is it otherwise not advisable to do such a thing ?
