Hi all!

        I'm testing packetfence-3.6.0-1.el6 on a CentOS 6.3, in inline mode,
aiming to build a captive-portal for an hotspot with a few hundreds users.

        We want users to authenticate to the captive portal for _every_ access,
even if they are made with the same device (same MAC address) and via the
same AP.

        While experimenting with registration.expire_mode=session I saw that the
pfdhcplistener regularly updates the end_time field in the iplog table
based on the lease_time of the DHCPACK it process.

        This means that despite the "registration.expire_session" setting, and
despite the "general.maintenance_interval", node sessions _CANNOT_ be
shorter than the lease-time defined in the DHCP negotiation. This is a
bit embarassing, as in network conf both default-lease-time and
max-lease-time ha a default of 86400 (aka: 1 day).

        Is this an expected behaviour?

        I'm asking this, 'cause in our case the lease time negotiated via DHCP
has no relationship with the lenght of the user session: user session can
be terminated (and actually should) even if the dhcp lease remain
associated with user client.

        Thanks in advance for any information.

        Regards,
        DV
