we wish that we can bound the user ip address with its username altogether
. The certain user can only access system through the certain computer.
is there any suggestion?

In LN there is a function called:
function long get.client.ip.address (ref string ip.address)

Description

Get the IP address of the local client. In case of Baan Windows this is the client machine on which BW is running. In case of Webtop, this is the client machine on which the Internet Browser is running

Arguments

ref string ip.address Output argument which will contain the IP address of the client on return of this function.

Return values

true Function succeeded, IP adress is filled.
false Function failed, client IP address is unknown.

that is a nice idea . but if a script is compliled to verify the matching between the username and its ip address, how can i make this script run automatically once the user login the system ?

You can use the user start up sessions (ttaad2105/6/7m000), or BMS (ttadv4188m000).

Enjoy :)

thanks i do think it will work
