Out-of-the-box unauthenticated users that interact with Content Server have access to a special account called #none. As a wise man MIGHT guess this is a way of saying "Here's your badge to access content with no account."
Great, but what if I wanted to grant read access to a particular account or accounts for guest?
For this, we need to add a configuration setting named "DefaultAccounts" to <install>/config/config.cfg. When we add this setting we use the name of the account along with a set of parenthesis detailing the access level allowed. Let's see this in action:
In this case guests accessing the system have read access to content with the Manuals or Contracts accounts.
So, don't forget:
#none grants access for content without accounts
#all grants access to content with any account
