Office 365 Single Sign-On (SSO)

Step 1: Prerequisites

1.1: Sync On-Premise Active Directory with Azure Active Directory

Note: Skip this step if don't want to use On-Premise Active Directory. 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.

1. Download the Azure AD Connect
2. Run the Azure AD installer on your domain machine and follow the setup.

1.2: Verify your UPN Domain in Azure Portal

1. In the Azure portal navigate to Azure Active Directory >> Custom domain names and click on Add custom domain.
   
2. Enter the full domain name in the right pane that pops up and click on Add domain.



3. 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.



4. Click on verify once you have added the entry
5. It can take anywhere from 15 minutes to 72 hours for the update to fully propagate, so it might take a while before you can complete the validation process. Validation affirms to Office 365 that you own the domain name your clients will later use to authenticate. You don’t need to have any servers within this domain for federation to function. All you need to complete this step is the domain itself that you can resolve from the Internet.

Step 2: 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

based on the User Store you are using:
• Login to miniOrange Admin Console.
• Navigate to Customization >> Login and Registration Branding
• Under Basic Settings, set the Organization Name as the custom domain name and Save. Once that is set, the branded login URL would be of the format https://<custom_domain>.miniorange.com/moas

Step 3: Choose Your User Directory

3.1: Setup AD as User Directory

1. Log in to miniOrange Admin Console.
2. From the Side Menu, Click on User Stores >> Add User Store

   

3. Select User Store type as AD/LDAP.



1. STORE LDAP CONFIGURATION IN MINIORANGE: Choose this option if you want to keep your configuration in miniOrange. If active directory is behind a firewall, you will need to open the firewall to allow incoming requests to your AD.
2. 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.



4. Enter LDAP Display Name and LDAP Identifier of your choice. Select Directory Type as Active Directory.
5. Enter the LDAP Server URL or IP Address against LDAP Server URL field.
6. Go to AD FS-> Domain-> respective Users -> Properties-> Attribute Editor. Now copy the value of distinguishedName and paste it against Bind Account DN.



7. Enter the valid password for the user from above step.
8. Search Base is the location in the directory where the search for a user begins.



9. If you want to add extra conditions on user search you can add it in Search Filter. Select a suitable Search Filter from the Drop-Down. To use custom Search Filter select "Custom Search Filter" option and provide the search filter in the input field that shows up.



10. You can also configure following options while setting up AD.




Here's the list of the attributes and what it does when we enable it. You can enable/disable accordingly.

Attribute	Description
Activate LDAP	All user authentications will be done with LDAP credentials if you Activate it
Sync users in miniOrange	Users will be created in miniOrange after authentication with LDAP

Allow users to change password	This allows your users to change their password. It updates the new credentials in your LDAP server
Enable administrator login	On enabling this, your miniOrange Administrator login authenticates using your LDAP server
Show IdP to users	If you enable this option, this IdP will be visible to users
Send Configured Attributes	If you enable this option, then only the attributes configured below will be sent in attributes at the time of login



11. Enable Send Configured Attributes and configure "objectguid" in both the text boxes that appear



12. Click on Save. After this, it will show you the list of User stores. Click on Test Configuration to check whether you have enter valid details. For that, it will ask for username and password.



13. On Successful connection with LDAP Server, a success message is shown.



14. Click on Test Attribute Mapping.



15. Enter a valid Username. Then, click on Test. Mapped Attributes corresponding to the user are fetched.



16. After successful Attribute Mapping Configuration, go back to the ldap configuration and enable Activate LDAP in order to authenticate users from AD/LDAP.
