SPD Server has a general ID that is called Anonymous. Any person can connect to the server by
using the eight-character user ID
anonymou and
no password. (There is an eight-character limit for user IDs.) All
resources that are created by the Anonymous user are accessible to
any other SPD Server user.
If you want to prevent Anonymous user access at your site, use the psmgr utility to
add a user named Anonymou to the
password database and keep the password secret.
