The password file contains details of user-IDs and passwords that the Fileshare Server uses when Fileshare Password Security is enabled. Because the information in the password file is encrypted for security reasons, you can only add records to and remove records from the password file using the Password File Maintenance Utility.
Use the /pf (password file) option to add or remove entries in the password file, for example:
fs /pf pass.dat [options]
