Considering that our indexed LDAP servers can handle 1,000,000+ queries/hour, that really isn't a justification for a local database. And userbases in constant flux are a lot happier without tiresome server-by-server alias table sync. Not that local DBs aren't good, but they are not mandated by performance concerns if architectures are built to support centralized directories. -Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] ------------------------------------ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
