Questions tagged [kerberos]

Kerberos is a computer network authentication protocol, which allows nodes communicating over a non-secure network to prove their identity to one another in a secure manner. Its designers aimed primarily at a client–server model, and it provides mutual authentication — both the user and the server verify each other's identity.

As many vendors have their own implementation of Kerberos, configuration details for each implementation is likely to vary. Here are some links that may help those troubleshooting Kerberos on commonly used paltforms.
