The Kerberos protocol defines how clients interact with a network authentication service. Clients obtain tickets from the Kerberos KDC and they present these tickets to servers when connections are established. Kerberos tickets represent the clients network credentials.
Given that Adesso operates in an "occasionally connected" manner, we enforce local access control and authentication. It's possible to coordinate authentication to an Adesso server with Active Directory (which is what also runs on a Domain Controller). However, we have no integration with Kerberos authentication.
