looking for a tool to change domain passwd and shell passwd

[heimdall]

Dear all,

I'm using samba as a PDC on a linux box with some windows 2k workstations
having a shell on the box.
It works great.
Now I'm looking for a script/tool that can change domain passwd and shell
passwd from the workstations in one step.
I thought first to code a cgi called by the workstations who will launch
passwd and smbpasswd. Or a client/server tool in java...
I havent found any wrapper of the CTR-ALT-DEL+Change-password command ..

Do someone know of some scripts/code/tools like that please ?

Thank you very much.

Regards,

Heimdall
