With SAS Information Delivery Portal 4.3 and later,
you can enable unchallenged access to the portal. When unchallenged
access is enabled, users can access the portal and interact with selected
content without providing a user ID and password. The option is similar
to the Public Kiosk feature in the SAS 9.1.3 release of the SAS Information
After you have enabled
unchallenged access, users can access the portal by entering the URL
When the SAS Information Delivery Portal Web application receives
this request, it does not display a logon page. Instead, it creates
a user session with the identity of a special user that you set up

Delivery Portal. The process differs depending on whether you enable
the option in an existing deployment or enable it during the process
of a new installation or a migration from SAS 9.1.3.
When implementing unchallenged
access, SAS administrators must be aware of important security considerations,
including precautions to take to ensure that content is not inadvertently

described in the next topic.
Unchallenged portal access
is supported only with SAS authentication. It is not compatible with
