When I change the password for a user via MMC in AD I can mark "User
must change password at next login" and the user is prompted to do so
when they log in.

When I change the password via ConsoleOne the user is not prompted to
change password. In order to do so they press Ctrl-Alt-Del > Change
Password, if they want their password changed.

How can I force a password change after I changed the password i
ConsoleOne for the user?

I'm running Windows 2003 SP1 and IDM2 with the latest patches.
Client is Windows 2000 SP4 and NW client 4.91 sp1 + patches

Thank you,
Kasper
