If you don't explicitly declare an SPN, Kerberos authentication works only under one of the following application pool identities: But these identities aren't recommended, because they're a security risk. As far as Internet Explorer is concerned, the ticket is an opaque blob. NTLM fallback may occur, because the SPN requested is unknown to the DC. You can change this behavior by using the authPersistNonNTLM property if you're running under IIS 7 and later versions. Security Keys utilize a secure challenge-and-response authentication system, which is based on ________. The system will keep track and log admin access to each device and the changes made. Kerberos authentication supports a delegation mechanism that enables a service to act on behalf of its client when connecting to other services. No importa o seu tipo de trabalho na rea de .

Using this registry key means the following for your environment: This registry key only works inCompatibility modestarting with updates released May 10, 2022. If a certificate can only be weakly mapped to a user, authentication will occur as expected. Under IIS, the computer account maps to Network Service or ApplicationPoolIdentity. If IIS doesn't send this header, use the IIS Manager console to set the Negotiate header through the NTAuthenticationProviders configuration property. For completeness, here's an example export of the registry by turning the feature key to include port numbers in the Kerberos ticket to true: More info about Internet Explorer and Microsoft Edge, Why does Kerberos delegation fail between my two forests although it used to work, Windows Authentication Providers , How to use SPNs when you configure Web applications that are hosted on Internet Information Services, New in IIS 7 - Kernel Mode Authentication, Request based versus Session based Kerberos Authentication (or the AuthPersistNonNTLM parameter), Updates to TGT delegation across incoming trusts in Windows Server.
