Zimbra Automation: How to change an LDAP attribute for all users
The purpose of this script is to show how a single attribute value can be changed for all users in LDAP. The reason I made this article was an incident, where all mobile users were unable to sync, because their zimbraCreateTimestamp attribute value was in the future. This script explains how to change the value of this attribute for all users.
