Recall & Review

beginner

What is LDAP in the context of authentication backends?

LDAP (Lightweight Directory Access Protocol) is a protocol used to access and manage directory information services. In authentication, it helps verify user credentials against a central directory like Active Directory.

What does OAuth provide in authentication systems?

OAuth is an open standard for access delegation. It allows users to grant limited access to their resources on one site to another site without sharing their credentials.

How does Airflow use LDAP for authentication?

Airflow can be configured to use LDAP to authenticate users by connecting to an LDAP server and verifying user credentials during login.

What is a key benefit of using OAuth over traditional username/password authentication?

OAuth allows users to authenticate using third-party providers (like Google or GitHub) without sharing passwords, improving security and user convenience.

beginner

Name two common authentication backends supported by Airflow.

Airflow supports LDAP and OAuth as common authentication backends to manage user access.

What does LDAP stand for?

A Local Data Access Program

B Linked Data Authentication Process

C Lightweight Directory Access Protocol

D Logical Directory Access Path

LDAP stands for Lightweight Directory Access Protocol, used for directory services and authentication.

Which of the following best describes OAuth?

A A file transfer protocol

B A database for storing user credentials

C A programming language

D A protocol for delegating access without sharing passwords

OAuth is a protocol that allows access delegation without sharing user passwords.

In Airflow, what is the purpose of configuring an LDAP backend?

A To manage database connections

B To authenticate users against a directory service

C To schedule tasks

D To store workflow logs

LDAP backend in Airflow is used to authenticate users by verifying credentials against a directory.

Which is a common OAuth provider used for authentication?

A Google

B MySQL

C Apache

D Docker

Google is a common OAuth provider allowing users to authenticate using their Google accounts.

What is a main advantage of using OAuth in applications?

A Users don’t need to share their passwords with the app

B It stores passwords securely in the app

C It speeds up database queries

D It encrypts all network traffic

OAuth lets users grant access without sharing passwords, enhancing security.
