In an application that means that if users are added to Windows or Active Directory Groups and your application depends on those new groups, you have to force users to log out and back in.

I think that has always been the case for AD accounts - it's certainly typical when I have adjusted groups on people's accounts to say, allow them access to a mapped network drive they have to log out and back in for the new groups to apply and gain access to resources.

Same goes for NTFS permissions. The group memberships go along with the Kerberos ticket that is made at logon time, so logging out and logging back in issues a new ticket with the up-to-date memberships. The confusing thing about it is that the behavior is different whether you log in explicitly via the browser login dialog, or whether you are automatically logged in via the auto-login dialog.

Those looking to set this up for an enterprise can likely follow the directions for using Group Policy or the Admin console to configure the AuthServerAllowlist policy.

Those looking to set this up for one machine only can also follow the Group Policy instructions:. In addition to setting the registry entry for AuthServerWhitelist you should also set AuthSchemes: "ntlm,negotiate" or just "ntlm" as appropriate for your situation.

Credentials can be persisted across requests on a connection. Negotiate authentication must not be used with proxies unless the proxy maintains a connection affinity a persistent connection with Kestrel.

The Negotiate handler detects if the underlying server supports Windows Authentication natively and if it is enabled. If the server supports Windows Authentication but it is disabled, an error is thrown asking you to enable the server implementation. When Windows Authentication is enabled in the server, the Negotiate handler transparently forwards authentication requests to it. The following APIs are used in the preceding code:.

Kerberos authentication on Linux or macOS doesn't provide any role information for an authenticated user. To add role and group information to a Kerberos user, the authentication handler must be configured to retrieve the roles from an LDAP domain.

Some configurations may require specific credentials to query the LDAP domain. The credentials can be specified in the following highlighted options:.

By default, the negotiate authentication handler resolves nested domains. In a large or complicated LDAP environment, resolving nested domains may result in a slow lookup or a lot of memory being used for each user. Nested domain resolution can be disabled using the IgnoreNestedGroups option. Anonymous requests are allowed. Use ASP. NET Core Authorization to challenge anonymous requests for authentication. Negotiate component performs User Mode authentication.

Service Principal Names SPNs must be added to the user account running the service, not the machine account. The instructions create a machine account for the Linux machine on the domain.

SPNs must be added to that machine account. When following the guidance in the Connect Azure Data Studio to your SQL Server using Windows authentication - Kerberos article, replace python-software-properties with python3-software-properties if needed. Once the Linux or macOS machine is joined to the domain, additional steps are required to provide a keytab file with the SPNs:.

The following code adds authentication and configures the app's web host to use HTTP. The configuration state of anonymous access determines the way in which the [Authorize] and [AllowAnonymous] attributes are used in the app.

The following two sections explain how to handle the disallowed and allowed configuration states of anonymous access. When Windows Authentication is enabled and anonymous access is disabled, the [ [Authorize] ] xref:Microsoft. AuthorizeAttribute and [AllowAnonymous] attributes have no effect. If an IIS site is configured to disallow anonymous access, the request never reaches the app.

For this reason, the [AllowAnonymous] attribute isn't applicable. When both Windows Authentication and anonymous access are enabled, use the [ [Authorize] ] xref:Microsoft. AuthorizeAttribute and [AllowAnonymous] attributes.
