For the Basic/NTLM/file - prompt via form Results Authorization
method, this setting controls what cookie type to use for
the Search Appliance's copy of the user's credentials.
With Basic/NTLM/file - prompt via form set, when a user
conducts a search for the first time, a form is presented (from
the Search Appliance) asking for a user and password. The user/pass is sent
back to the user as a cookie from the Search Appliance for use in future
searches without having to re-prompt. The user/pass is also
simultaneously used to validate search results via HTTP Basic/NTLM or
Windows/SMB file access.
The Basic/NTLM/file Cookie Type setting controls whether this
cookie from the Search Appliance should be Persistent (retained
long-term - a year - so the user does not have to log in at each new
session) or Session (discarded after browser closure for
security).
Note that the cookie for Basic/NTLM/file Cookie Type is distinct
from the Login Cookies; they are used for different access
methods. The former originates from the Search Appliance and is only ever
sent to/from the user and the Search Appliance: non-cookie-based access
methods are then used from the Search Appliance to the result URLs for
actual authentication. Login Cookies, however, originate from a
third-party form-based login system, and pass from the login server to
the user to the Search Appliance to the result URLs.
