What is an spn?

SPN typically stands for 'Service Provider Network' or 'Service Principal Name,' depending on the industry context. In the context of IT and cybersecurity, an SPN (Service Principal Name) is a unique identifier for a service instance in a network, often used in Kerberos authentication within Windows environments. SPNs allow clients to uniquely identify and authenticate services on a network, ensuring secure service-to-service communication. Correct SPN configuration is crucial for seamless authentication and functionality of networked services.
