An AS400 user and password would be required?

[Profound Logic]

Question:
An AS400 user and password would be required to access programs as opposed to web access?

Answer:
There are a number of options. You can have programs require sign on using AS/400 profiles, or you can elect to run them in "anonymous" sessions where system sign on is not required. When signing in, normal OS/400 authorities are in play for the signed in user profile.

When running anonymous sessions, users come in under a generic OS/400 profile. This might be appropriate for "public" type applications that show information that anybody can view -- i.e. product listing on website, etc. Profound UI also supports basic authentication and single sign-on.
