Hello everyone. I hope most of you here are familiar with the Kerberos authentication service. Its version 5 is often claimed to be a very secure implementation on open networks. With all the key exchanges that occur between the Authorization Server, the TGS, the application server and the client station, I wanted to know its advantage over the more traditional Unix/linux and windows network. Does Unix also employ such an exchange of tickets between the client and servers, or is the network password the only relevant authenticator?
