Authentication. Users must provide the relevant credentials before they can access resources on the network.
Security groups. IT admins organize users into groups. ...
Group policy. There are a large number of policies in Active Directory that define who can access computers remotely or configure browser security settings.

AD authentication is a Windows-based system that authenticates and authorizes users, endpoints, and services to Active Directory.

What is Active Directory used for?

Active Directory (AD) is Microsoft's proprietary directory service. It runs on Windows Server and enables administrators to manage permissions and access to network resources. Active Directory stores data as objects. An object is a single element, such as a user, group, application or device such as a printer.

Is LDAP same as SSO?

SSO is a method of authentication in which a user has access to many systems with a single login, whereas LDAP is a method of authentication in which the protocol is authenticated by utilizing an application that assists in obtaining information from the server.

What is difference between AD and ADFS?

Since Active Directory stores the information of all users (accounts and passwords), it acts as the base identity store. ADFS uses all of this identity information in AD, and makes it available externally, outside your network. This information can then be used by other organizations and applications.

The way you begin an LDAP session is by connecting to an LDAP server, known as a Directory System Agent, which “listens” for LDAP requests. “Domain controller” is another name for the server responsible for security authentication requests. For users, domain control (DC) is the centerpiece of Active Directory.

What is LDAP authentication and how it works?

LDAP authentication involves verifying provided usernames and passwords by connecting with a directory service that uses the LDAP protocol. Some directory-servers that use LDAP in this manner are OpenLDAP, MS Active Directory, and OpenDJ.

What is the end goal of Azure?

The end-goal for many environments is to remove the use of passwords as part of sign-in events. Features like Azure password protection or Azure AD Multi-Factor Authentication help improve security, but a username and password remains a weak form of authentication that can be exposed or brute-force attacked.

What is multifactor authentication?

Multi-factor authentication is a process where a user is prompted during the sign-in process for an additional form of identification, such as to enter a code on their cellphone or to provide a fingerprint scan.

What does it mean when a user can't sign in?

Password change - when a user knows their password but wants to change it to something new. Password reset - when a user can't sign in, such as when they forgot password, and want to reset their password. Account unlock - when a user can't sign in because their account is locked out and want to unlock their account.

What is self service password reset?

Self-service password reset gives users the ability to change or reset their password, with no administrator or help desk involvement. If a user's account is locked or they forget their password, they can follow prompts to unblock themselves and get back to work. This ability reduces help desk calls and loss of productivity when a user can't sign in to their device or an application.

Why is Azure AD important?

What is Azure authentication?

One of the main features of an identity platform is to verify, or authenticate, credentials when a user signs in to a device, application, or service. In Azure Active Directory (Azure AD), authentication involves more than just the verification of a username and password. To improve security and reduce the need for help desk assistance, Azure AD authentication includes the following components: 1 Self-service password reset 2 Azure AD Multi-Factor Authentication 3 Hybrid integration to write password changes back to on-premises environment 4 Hybrid integration to enforce password protection policies for an on-premises environment 5 Passwordless authentication

Does Azure AD block passwords?

By default, Azure AD blocks weak passwords such as Password1. A global banned password list is automatically updated and enforced that includes known weak passwords. If an Azure AD user tries to set their password to one of these weak passwords, they receive a notification to choose a more secure password.

What is a TGT in KDC?

This is called as Ticket Granting Ticket (TGT). TGT contain two things, 1) Copy of session key that KDC use to communicate with Dave. This is encrypted with KDC’s long-term key. 2) Copy of session key that Dave can use to communicate with KDC. This is encrypted with Dave’s long-term key so only Dave can decrypt it.

How does KDC work?

1) Dave sends user name and his long-term key to KDC (Domain Controller). 2) KDC, checks user name and long-term key with its database and verify identity. Then its generates TGT (Ticket Granting Ticket). It includes copy of session key which KDC use to communicate with Dave. This is encrypted with KDC’s long-term key.

What is KDC responsible for?

KDC is responsible for two main functions. 1) Authentication Service (AS) 2) Ticket Granting Service (TGS) In example, when Dave logs in to the system, it needs to prove KDC that he is exactly the same person that he claims to be.

In order to protect this communication, they agreed on a common secret 1234 to use to verify their identities before exchange data. When Dave make initial communication, he passes his secret to server A and say “I’m Dave”. Server A checks the secret to see if it’s true.

What are the components of Kerberos?

As the three-headed dog, Kerberos protocol has three main components. 1) A Client. 2) A Server. 3) A trusted authority to issue secret keys. This trusted authority is called as Key Distribution Center (KDC). Before we look in to Kerberos in detail, better to understand how typical key exchange works.

Can Dave decrypt a session key?

This is encrypted with Dave’s long-term key so only Dave can decrypt it. Once Dave receive this key, he can use its long-term key to decrypt the session key. After that, for all the future communication with KDC will be based on this session key. This session key is temporally and have its TTL (Time to Live) value.
