Setting up integrated windows authentication
The following guide will assist you in configuring your application to use Integrated Windows Authentication (IWA).
Note, that we recommend that you use a strong authentication mechanism such as OpenID Connect, where you have the ability to enforce multifactor authentication on users attempting to access your application. Access Manager fully supports modern OIDC providers such as Microsoft Entra ID and Okta.
Part 1: Configure the SPN
To ensure kerberos authentication works correctly you'll need to register an SPN for the Access Manager service account.
The SPN must be in the format of HTTP/{dnsName}
where {dnsName}
is the external-facing DNS hostname used by the clients.
Part 2: Configure Lithnet Access Manager
Open the Lithnet Access Manager Service Configuration Tool
Select the
App configuration\User authentication
pageSelect
Integrated windows authentication
as the authentication providerSelect
Negotiate
for the authentication scheme.
The use of NTLM and basic auth is not recommended and are provided for testing purposes only.
To restrict clients to the use of Kerberos only, disable incoming NTLM authentication for the server using group policy.
