User management in LDAP?

Question

LDAP

There is a certain structure - linux servers, LDAP (OpenLDAP), mail (postfix) is spinning on them. The mail user base is separate from LDAP.
I would like to rearrange a bit. I would like to have a common database of users and their mailboxes in LDAP and implement the Zimbra campaign.
Prompt a separate tool for managing users in LDAP. I know about GoSa and Zivios. Interested - maybe something simpler - just through the web face in a simple human-oriented form to add users, assign mailboxes to them.
Well, let users in only to themselves in order to change passwords.

Answer 1

phpldapadmin, but you need to tweak the templates.

Answer 2

Apache directory studio is not bad either
