Configuring Basic, Digest, NTLM/Kerberos and Negotiate Authentication

Acunetix 360 supports Basic, Digest, NTLM/Kerberos and Negotiate authentication mechanisms. This enables you to configure scans for websites that require those types of authentication.

Basic, Digest, NTLM/Kerberos and Negotiate Authentication Fields

This table lists and explains the fields in the Basic, Digest, NTLM/Kerberos and Negotiate Authentication section.



Basic, Digest, NTLM/Kerberos, Negotiate Authentication

Select to enable Basic, Digest, NTLM/Kerberos or Negotiate Authentication.


This is the type of authentication:

  • Basic
  • NTLM
  • Kerberos
  • Digest
  • Negotiate

URL Prefix

Enter the URL prefix that determines the scope of the authentication method.


Enter the username.


Enter the password, masked by asterisks.


Enter the domain setting, which should be the value of the domain name for Windows systems, not the hostname of the site. This field is optional, for when the domain is required in Windows environments only.

Do not expect challenge (Basic Authentication)

Select to enable authentication, even if the server does not send an authentication challenge. This is an option that specifies whether the Basic Authentication credentials should be sent in each request without expecting a 401 Authentication challenge from the server.
