Active Directory
Azure Active Directory (AAD) is Microsoft's cloud user store that powers Office 365 and other associated Microsoft cloud services. It offers complementary features to users, groups, and devices found in AD, but they must be part of AAD first.
AAD interacts with different clients via different methods, communicating via unique endpoints. For example, when a user authenticates to a Windows 10 machine registered to AAD, the machine is logged in via an /username13 endpoint.
Microsoft Azure AD is a cloud-based service that enables administrators to manage access privileges and end-user identities.

Active Directory Overview
Active Directory is a powerful tool for managing user access and identities, but it's not the only game in town. Azure Active Directory (AAD) is Microsoft's cloud user store that powers Office 365 and other associated Microsoft cloud services.
AAD offers complementary features to the users, groups, and devices found in AD, but these objects must first be part of AAD. In order to apply these features, users, groups, and devices must be part of AAD, just like objects need to be part of AD before Group Policy Objects (GPOs) can be applied.
Azure AD is a cloud-based service that enables administrators to manage access privileges and end-user identities. It provides access management, identity protection, and a user directory.
Azure AD allows users to centralize authentication into applications using single sign-on (SSO) security. This means users only need to log in once to access multiple applications.
AAD interacts with different clients via different methods, each communicating via unique endpoints. For example, when a user authenticates to a Windows 10 machine registered to AAD, the machine is logged in via an /username endpoint.

Federation and Authentication
Federation and authentication are crucial components of an Okta Azure AD integration. Federation involves mapping identities between an identity provider (IDP) and service provider (SP), creating a secure agreement between the two entities for authentication.
Explore further: Azure Ad Federation
In a federated model, authentication requests are sent to Azure Active Directory (AAD) first, which checks for federation settings at the domain level. If a domain is federated with Okta, traffic is redirected to Okta.
Basic and modern authentication have different endpoints and behaviors. Basic authentication sends the username and password to Okta from the basic authentication endpoint (/active), while modern authentication redirects the user to Okta via an embedded web browser from the modern authentication endpoint (/passive).

Federation
Federation is a secure way to connect an identity provider (IDP) and a service provider (SP), creating an agreement between the two entities for authentication. This connection is crucial for accessing resources like Office 365 and Azure AD.
In a federated environment, you have to authenticate against the IDP, such as Okta, before being granted access to resources. The IDP is responsible for registering a device for a hybrid domain join, which requires a federation identity.
A federated domain is checked for federation settings at the domain level, and if it's federated with Okta, traffic is redirected to Okta. Okta's sign-in policy understands the relationship between authentication types and their associated source endpoints and makes a decision based on that understanding.
There are different authentication flows in a federated environment, including basic authentication and modern authentication. Basic authentication sends the username and password directly to Okta, while modern authentication redirects the user to Okta via an embedded web browser.
Here are the differences between basic and modern authentication:
The default O365 sign-in policy in Okta is designed to block all requests, including both basic and modern authentication. However, you can create a custom policy to allow modern authentication to pass through.
About
As a system administrator, I've seen firsthand how important it is to have a solid understanding of federation and authentication. Federation allows different organizations to share resources and information securely, while authentication ensures that only authorized users have access to those resources.
Federation protocols like SAML and OAuth enable seamless communication between systems, making it possible to access resources from one organization within another organization's system. This is particularly useful in scenarios where multiple organizations need to collaborate on a project.
The concept of identity federation is built on the idea of a single identity being recognized across multiple organizations, eliminating the need for separate logins and passwords for each system. This approach has been adopted by many companies, including Google and Microsoft.
Authentication mechanisms like username/password combinations, two-factor authentication, and smart cards provide an additional layer of security to prevent unauthorized access to systems and resources. In some cases, these mechanisms can be combined to provide even greater security.
Microsoft vs. Background
Microsoft and Okta offer distinct identity management solutions, making direct comparisons challenging.
Microsoft's solution is provided in a hybrid model, combining on-premises (Microsoft Active Directory) and cloud (Azure Active Directory) components for seamless integration.
For your interest: Sync Active Directory with Azure Ad
This integration enables on-premise AD users to access cloud resources and vice versa, a feature that's particularly useful for organizations with both on-premises and cloud infrastructure.
Okta's solution is called Identity Cloud, which includes two products: Workforce Identity and Customer Identity.
Workforce Identity is the solution comparable to Azure AD, focused on end-users and administrators, while Customer Identity is geared towards developers.
Microsoft Azure AD is a broad tool covering a wide variety of resources, providing features like single sign-on (SSO), privileged access management (PAM), identity governance, and multi-factor authentication (MFA).
Okta Workforce Identity, on the other hand, is more cloud- and vendor-agnostic, promoting use in any environment and with any other services.
Hybrid Domain Join
Everyone's going hybrid, with remote work becoming the new normal. This means that enterprises need choice, including choice of device and tools, and the ability to leverage hybrid domain joined capabilities of Microsoft Office 365.
Okta is uniquely suited to help enterprises navigate this shift, providing a premier identity and access management solution that can move to the cloud for all identity needs and take advantage of new Azure Active Directory (AAD) features.

Daily logins on a Windows 10 Hybrid Domain Joined machine will authenticate against AAD to receive a Primary Refresh Token (PRT) that is granted at Windows 10 device registration.
Okta provides flexibility to use custom user agent strings to bypass block policies for specific devices such as Windows 10, allowing for seamless login experiences.
A good solution is to disable all Microsoft services that use legacy authentication and adjust the O365 sign-in policy within Okta to allow only legacy authentication within the local intranet.
Windows Autopilot can be used to automatically join machines to AAD, easing the transition from Windows 7 to Windows 10.

Security and Access Control
Azure AD and Okta offer robust security features to protect your organization's data. Both services provide conditional access policies to control user access, but Okta's policy is more restrictive.
Okta's zero-trust protocol treats all users as untrusted, even administrators, and locks them out with automated locks if unusual activity is detected. This approach may cause more friction for users who need to re-authenticate frequently.
Azure AD uses a security token to separate servers and users, and its strict trust system verifies user identities. This system helps prevent unauthorized access to sensitive data.
Conditional Access policies in Azure AD can detect when a user moves off the network and signal for a fresh login with MFA, which initiates an Okta login.
Active Directory vs. Support Options
When evaluating Azure Active Directory (Azure AD) and Okta for your organization's identity and access management needs, it's essential to consider the support options available.
Azure AD provides a range of support packages, including the Basic plan, which is free and offers self-help resources and documentation.
The Developer plan costs $29/month and includes email support during business hours with a response within 8 hours.
For 24/7 support, you can opt for the Standard plan, which costs $100/month and provides response times of 1-8 hours.
The Professional Direct plan is the most premium option, costing $1,000/month for 24/7 support with response times of 1-4 hours.
In contrast, Okta offers a Basic plan with a 24-hour response time for support requests by phone or email during business hours.
Okta's Premier plan guarantees a response to support requests within one hour 24/7/365, and also includes discounts on live online training classes.
Here's a comparison of the support options offered by Azure AD and Okta:
Conditional Access
Conditional Access is a powerful tool that allows you to control access to your organization's resources based on various conditions. It's like having a gatekeeper that checks who's allowed to enter and what they can do once inside.
Okta and Azure AD Conditional Access both have policies, but Okta's policy is more restrictive. For example, if you want to require MFA while a user is off the network, you'd create a strict policy in Okta, whereas in Conditional Access, you'd configure it for in and out of network.
Conditional Access can detect when a user moves off the network and signal for a fresh login with MFA. This initiates an Okta login, which then returns the MFA claim to Microsoft, fulfilling the MFA requirement.

Here's a comparison of Okta and Conditional Access policies:
By using Conditional Access, you can ensure that your organization's resources are only accessible to authorized users, even when they're off the network. This adds an extra layer of security and helps prevent unauthorized access.
Identity and Access Control
Azure Active Directory (Azure AD) is a cloud-based service that enables administrators to manage access privileges and end-user identities.
Azure AD uses a security token to separate servers and users completely, providing a strict trust system for verification. This ensures that users are treated as safe, even administrators, until unusual activity is detected.
Conditional Access policies in Azure AD provide granular O365 application actions and device checks for hybrid domain joined devices. This allows for more flexibility in managing access.
Okta's policy is more restrictive than Azure AD's, requiring a strict policy of ALWAYS MFA, whereas Azure AD's policy can be configured for in and out of network.
Okta's zero-trust protocol treats no users as safe, not even administrators, and puts automated locks in place at the slightest sign of unusual activity. This requires re-authentication, which may provide more friction for users.
Azure AD offers complementary features to users, groups, and devices, but these must first be part of AAD. This allows for additional features to be applied to these objects.
Here are the key differences between Azure AD and Okta's authentication mechanisms:
Azure AD interacts with different clients via different methods, communicating via unique endpoints. For example, when a user authenticates to a Windows 10 machine registered to AAD, the machine is logged in via an /username13 endpoint.
