We also encourage you to explore all things Zimbra with our team and members of the community.
I want to know if there are some information about custum queries in the zimbra admin page like reports of users with above 90% of user space and other useful reports
I know you can do _more_ reporting (such as quota) via command line.
All my reports from the Admin Page (Saved Searches) are basically glorified LDAP searches (syntax included!) - with that said, Quota usage is probably not in LDAP ..emphasis on the "Lightweight"
There are command line tools to get tons of information..
