Office365 Device Restriction
What is Office365 Device Restriction?
Device Restriction is a way of allowing your employees to access certain resources only from a specific number of devices. Device Restriction is a widely used feature for enterprise applications like Office365.
- In Office365 device restriction, the admin allows end-users to add a fixed number of devices as trusted devices for their account. Once a device is registered for a user, they will be allowed to login without any restriction on that device only.
- When a user initiates the login process for an application for which Device Restriction is enabled, the attributes related to the user's browser session are captured for evaluations.
- Based on these attributes, the miniOrange Adaptive Engine checks and evaluates the decision for that particular user. (i.e Allow, Deny or Challenge with 2FA).
- Based on the decision calculated, the user is redirected to the appropriate action. (i.e Allowed to login if the decision is allow, denied to login if decision is deny or challenged with 2FA if the decision is challenge)
Connect with External Source of Users
miniOrange provides user authentication from various external sources, which can be Directories (like ADFS, Microsoft Active Directory, Azure AD, OpenLDAP, Google, AWS Cognito etc), Identity Providers (like Shibboleth, Ping, Okta, OneLogin, KeyCloak), Databases (like MySQL, Maria DB, PostgreSQL) and many more.
1. Sync On-Premise Active Directory with Azure Active Directory
NOTE: If you want to use your On-Premise Active Directory as a user store to Single Sign-On into Office 365 then follow the below steps to sync your AD and Azure AD.
- Download the Azure AD Connect
- Run the Azure AD installer on your domain machine and follow the setup.
2. Verify your UPN Domain in Azure Portal
- In the Azure portal navigate to Azure Active Directory >> Custom domain names and click on Add custom domain.
- Enter the full domain name in the right pane that pops up and click on Add domain.
- A new window will open up with TXT/MX records for the domain. You will have to add the resented entry in your domain name registrar.
- Click on verify once you have added the entry
Follow the Step-by-Step Guide given below to configure Office 365 Device Restriction
1. Setup a Custom Branded URL in miniOrange Admin Console
Single Sign-On into Office 365 requires a custom branded URL to be set. Access to miniOrange and connected resources will need to be through the custom branded URL in the format: https://<custom_domain>.xecurify.com/moas
- Login to miniOrange Admin Console.
- Click on Customization in the left menu of the dashboard.
- In Basic Settings, set the Organization Name as the custom_domain name.

- After downloading the script, Open PowerShell run the federate_domain script using:
powershell -ExecutionPolicy ByPass -File federate_domain.ps1
- Your domain is now federated. Use the commands below to check your federation settings:
4. Configure Device Restriction: Restricting access by Limiting the number of devices
Using Adaptive Authentication you can also restrict the number of devices the end user can access the Services on. You can allow end users to access services on a fixed no. of devices. The end users will be able to access services provided by us on this fixed no. of devices.
You can configure Adaptive Authentication with Device Restriction in following way

6. Configure Your User Directory (Optional)
miniOrange provides user authentication from various external sources, which can be Directories (like ADFS, Microsoft Active Directory, Azure AD, OpenLDAP, Google, AWS Cognito etc), Identity Providers (like Okta, Shibboleth, Ping, OneLogin, KeyCloak), Databases (like MySQL, Maria DB, PostgreSQL) and many more.

- STORE LDAP CONFIGURATION ON PREMISE: Choose this option if you want to keep your configuration in your premise and only allow access to AD inside premises. You will have to download and install miniOrange gateway in your premise.
In Active Directory, go to the properties of user containers/OU's and search for Distinguished Name attribute.
Enter the valid Bind account Password.
Click on Test Bind Account Credentials button to verify your LDAP Bind credentials for LDAP connection.
Search Base is the location in the directory where the search for a user begins. You will get this from the same place you got your Distinguished name.
