Turning off password checking for a user

The administrator can, of course, switch off password checking at any time for a user (even if the password has expired). Follow the directions in the Enabling password checking for users section above, only select Don't check password, which submits the appropriate Adminp request. However, if the ID's password has already expired, the user will need to change their password to reset the password structure inside the ID file. From then on, no client-side password checks are carried out until the ID is re-enabled for password checking.

What about making the workstation system clock sync to a time server?
