our student organization is using Zimbra 8.0 Open Source version. Our central user database is running on separate LDAP server.
Zimbra is configured to use that external LDAP and it works perfectly - just creation of users in user database is propagated to Zimbra by regularly running script - therefore creation of users is not real-time obviously.
Please is there some way how to autopropagate users to Zimbra? I guess this could work in a way, that if some unknown user is trying to log in - Zimbra would check its credetials in external LDAP and if auth would be successful, it would create his account in internal Zimbra account.
