Microsoft Internet Security and Acceleration Server 2000


The ISA Web proxy service includes a pointer to this structure when it is authenticating a user with either anonymous or Basic authentication schemes. If your filter should be notified for this event, it should register for the SF_NOTIFY_AUTHENTICATION event.

typedef struct _HTTP_FILTER_AUTHENT {
  CHAR * pszUser;
  DWORD cbUserBuff;
  CHAR * pszPassword;
  DWORD cbPasswordBuff;


Points to a string containing the user name for this request. An empty string indicates an anonymous user.
The size of the buffer pointed to by pszUser. This is guaranteed to be at least SF_MAX_USERNAME.
Points to a string containing the password for this request.
The size of the buffer pointed to by pszPassword. This is guaranteed to be at least SF_MAX_PASSWORD.


When the server is about to authenticate the client, this structure is pointed to by the pvNotification parameter in the HttpFilterProc function when the notificationType parameter is SF_NOTIFY_AUTHENTICATION. The pszUser and pszPassword members contain the information sent by the client. After exiting this function, these values must represent a valid Windows user account and password. ISA Web proxy will then impersonate this account to gain access to resources. If the authentication method used is integrated Windows authentication, the password value will not be available.
