This is from the release notes:

the WCS Password

You can change the WCS application root user or FTP user password. This option provides a safeguard

if you lose the root password. An executable was added to the installer /bin directory (passwd.exe for

Windows and passwd.sh for Linux). Follow these steps to recover the passwords and regain access to

WCS.

Note If you are a Linux user, you must be the root user to run the command.

Step 1 Stop WCS.

Step 2 On a Windows operating system, change to the WCS bin folder. (Linux does not have a WCS bin folder.)

Step 3 Perform one of the following:

Enter passwd root-user to change the password on the root account for WCS (not the

root account for access to the operating system on which WCS is running). The newpassword is the root

login password you choose.

or

Enter passwd location-ftp-user to change the FTP user and password.

The newuser and newpassword are the FTP user and password you choose.

Step 4 The following options are available with these commands:

? -q ? to quiet the output

? -pause ? to pause before exiting

? -gui ? to switch to the graphical user interface

? -force ? to skip prompting for configuration
