I would like to use Microsoft Active
Directory (AD) to authenticate
remote access users connecting to the
VPN3005 concentrator. Everything is
working fine but I want the VPN3k to use
microsoft ds (tcp port 445) instead of
netbios (tcp port 139) when it communicates with the AD server.
In the vpn 3005 I specified port 445
as the communication port between vpn3k
and the AD server but in my tcpdump,
i see this:
[Expert@cp]# tcpdump -i eth1 -n host 192.168.1.4

obviously, it is using port 139 instead
of port 445.
How can I fix this on the vpn3k? Thanks.
