Help with LDAP and ticket stats

I’ve got RT successfully installed on Redhat’s Fedora Core 5 via a yum
install. It will probably be used for manual ticket creation (granted rt
is designed to autocreate a ticket via an email queue).

For manual creation, it would be nice to enter a person’s name and have rt
query an existing LDAP server to show available people from whom to select.

Secondly, what is the easiest way, via the web interface, to create a monthly
report of tickets closed?

We will also want to create queues for different departments, so having a
monthly summary reflecting closed tickets per department, in a single-page,
would be most appreciated.

Thanks for any help.
