Which authentication method allows a user to log in to an SSO-enabled Cisco Unified Communications application by utilizing a Microsoft Windows login, thereby not requiring any credentials to be entered?
Click on the arrows to vote for the correct answerA. B. C. D.
The authentication method that allows a user to log in to an SSO-enabled Cisco Unified Communications application by utilizing a Microsoft Windows login, thereby not requiring any credentials to be entered, is Kerberos.
Kerberos is a network authentication protocol that uses a trusted third-party authentication server to provide secure authentication for clients and servers in a networked environment. When a user attempts to log in to a Kerberos-enabled application, the client sends a ticket request to the authentication server. The authentication server responds with a ticket-granting ticket (TGT), which the client uses to request service tickets from the appropriate service server. The service server then authenticates the client and grants access to the requested service.
Kerberos is a widely used authentication method in enterprise environments and is commonly used for single sign-on (SSO) authentication. With Kerberos-based SSO, users can log in to multiple applications without having to enter their credentials multiple times. Instead, the user logs in to the network once, and then the network handles authentication for all the applications the user accesses.
Smart Card authentication requires the use of a physical smart card containing user credentials, while OAuth is an open standard for authorization that allows third-party applications to access a user's data without the user having to share their credentials. Form-based authentication requires the user to enter their credentials manually into a login form. Therefore, none of these methods allow for a user to log in to an SSO-enabled Cisco Unified Communications application by utilizing a Microsoft Windows login, without requiring any credentials to be entered.
