HTTP_AUTH_STATUS enumeration (http.h)

The HTTP_AUTH_STATUS enumeration defines the authentication state of a request.

This enumeration is used in the HTTP_REQUEST_AUTH_INFO structure.

Syntax

typedef enum _HTTP_AUTH_STATUS {
  HttpAuthStatusSuccess,
  HttpAuthStatusNotAuthenticated,
  HttpAuthStatusFailure
} HTTP_AUTH_STATUS, *PHTTP_AUTH_STATUS;

Constants

 
HttpAuthStatusSuccess
The request was successfully authenticated for the authentication type indicated in the HTTP_REQUEST_AUTH_INFO structure.
HttpAuthStatusNotAuthenticated
Authentication was configured on the URL group for this request, however, the HTTP Server API did not handle the authentication. This could be because of one of the following reasons:


  • The scheme defined in the HttpHeaderAuthorization header of the request is not supported by the HTTP Server API, or it is not enabled on the URL Group. If the scheme is not enabled, the AuthType member of HTTP_REQUEST_AUTH_INFO is set to the appropriate type, otherwise AuthType will have the value HttpRequestAuthTypeNone.

  • The authorization header is not present, however, authentication is enabled on the URL Group.


The application should either proceed with its own authentication or respond with the initial 401 challenge containing the desired set of authentication schemes.
HttpAuthStatusFailure
Authentication for the authentication type listed in the HTTP_REQUEST_AUTH_INFO structure failed, possibly due to one of the following reasons:

  • The Security Service Provider Interface (SSPI) based authentication scheme failed to successfully return from a call to AcceptSecurityContext. The error returned AcceptSecurityContext is indicated in the SecStatus member of the HTTP_REQUEST_AUTH_INFO structure.

  • The finalized client context is for a Null NTLM session. Null sessions are treated as authentication failures.

  • The call to LogonUser failed for the Basic authentication.
