Problems with settings ends statement (was: Remove Lease via omshell)

[Gmail]

Hello List!

I'm having a problem with removing lease over omshell.

I have the same configuration as Marc described in his mail a couple
days ago
(https://lists.isc.org/pipermail/dhcp-users/2010-January/010754.html)

But when I try to set ends statements to the value 00:00:00:00 and
update it - I receive "Permission denied" error.

Here is full log of the session:

Oh, and I'm using modified version of dhcp3-server under Debian Lenny:

Description: DHCP server for automatic IP address assignment
This is the server from version 3 of the Internet Software Consortium's
implementation of DHCP. For more information, visit
http://www.isc.org. 

Dynamic Host Configuration Protocol (DHCP) is a protocol like BOOTP
(actually dhcpd includes much of the functionality of bootpd). It
gives client machines "leases" for IP addresses and can automatically
set their network configuration. 

This server can handle multiple ethernet interfaces.


I've build it from source package and just uncomment #define USE_SOCKETS
in includes/site.h file for support of 82 option.
