Changing the Windows Authentication Protocol
By default, in Orchestrator, the [NTLM authentication protocol][1] is used when logging in with your Active Directory credentials.

To switch to [Kerberos][2], you are required to switch the application pool to NetworkService and register the Service Principal Name (SPN) which exists in the Active Directory for the domain account used to run the service with which the client is authenticating.
To perform this change, perform the following steps:
To check that Kerberos is used:
- Log in to Orchestrator using AD credentials.
- Open Event Viewer.
- Look for the Microsoft Windows security audit and select it. Details about the action are updated on the General tab.

Under the Detailed Authentication Information section, the Logon Process should be Kerberos, as displayed in the following screenshot.
