The Kerberos access control system is widely used to implement authentication and authorization systems on both Unix and Windows platforms. LDAP allows services on a network to share information about users and their authorizations in a standardized, open format. Active Directory uses LDAP in combination with Kerberos. In this video, you learn how these two protocols work together.
- [Instructor] The Kerberos access control system…is widely used to implement…authentication and authorization systems…on both UNIX and Windows platforms.…It is one of the core protocols…underlying Microsoft Active Directory.…Kerberos is a ticket based authentication system…that allows users to authenticate to a centralized service…and then use tickets from that authentication process…to gain access to distributed systems…that support Kerberos authentication.…Here's how Kerberos works.…
An end user wants to gain access to a service…that supports Kerberos.…We sometimes refer to this service…as Kerberized service.…First, the end user uses a Kerberos client…on his or her system…to provide a user name and password.…The client then creates a clear text authentication request…that sends to an authentication server.…The authentication server…then looks up the user in its database…and retrieves the user's password.…It sends two messages back to the client.…
The first is a randomly generated session key…used for future communication…
