Since my organization has decided to move it's over to Zimbra, we thought me might take advantage of the world of LDAP. Now we are lucky enough to be able to install all of this from scratch. If we decide we want to take advantage of LDAP would the people out there in the Zimbra world recommend I go with a plain implementation of LDAP and integrate Zimbra into that. Or should I install ZimbraLDAP and integrate everything else into it.

And yes I know Zimbra uses OpenLDAP version 2.2.28.

Thanks for your recommendation it is much appreciated!
