About HTTP 401 Response

The HTTP 401 Response action sends an HTTP 401 Authorization Required Response page to capture HTTP Basic or Negotiate authentication.
For a per-request policy subroutine, HTTP 401 Response supports HTTP Basic authentication only.
The HTTP 401 Response action provides up to three branches: Basic, Negotiate, and fallback. Typically, a basic type of authentication follows on the Basic branch and a Kerberos Auth action follows on the Negotiate branch.
An HTTP 401 Response action provides these configuration elements and options.
Basic Auth Realm
Specifies the authentication realm for use with Basic authentication.
HTTP Auth Level
Specifies the authentication required for the policy.
  • none
    - specifies no authentication.
  • basic
    - specifies Basic authentication only.
  • negotiate
    - specifies Kerberos authentication only.
    This option is not available for a per-request policy subroutine.
  • basic+negotiate
    - specifies either Basic or Kerberos authentication.
    This option is not available for a per-request policy subroutine.
The action provides customization options that specify the text to display on the screen.
