cable network.

read/write privileges and a several interfaces in use with just read privileges.
• DNS force transfer—A method for a site to manually force an update on a secondary server when
the primary server has newer information.
• LDAP log and error messages—Messages that indicate progress in accessing an LDAP server.
This feature makes it easier to diagnose problems interfacing to LDAP.
• Improved server, GUI and CLI performance—A data structure enhancement that increases
processing speed and new lease generation when a large number of scopes are configured.
