Configure OneLogin Single Sign-On (SSO) with OAuth for WordPress

Overview

Set up Single Sign-On (SSO) on OneLogin using the OAuth & OpenID Connect Single Sign-On plugin for WordPress. Implementing OneLogin OAuth SSO allows users to securely log in to your websites and applications using a single set of OneLogin credentials.
In this setup, OneLogin acts as the OAuth Provider, while WordPress acts as the OAuth Client. OneLogin OAuth SSO for WordPress enables a seamless login experience between the two platforms, eliminating the need for users to remember multiple usernames and passwords.
The OneLogin OAuth SSO plugin also offers advanced features such as user profile attribute mapping, role mapping, and role-based access control for user profiles. Additionally, you can secure your entire WordPress site behind Single Sign-On (SSO). The OneLogin OAuth SSO for WordPress plugin enhances user authentication and secures the login process. Follow the step-by-step guide below to install and configure the plugin.

Pre-requisites : Download And Installation

• Log into your WordPress instance as an admin.
• Go to the WordPress Dashboard -> Plugins and click on Add New.

Step 3: User Attribute Mapping

• User Attribute Mapping is mandatory for enabling users to successfully login into WordPress. We will be setting up user profile attributes for WordPress using below settings.

Finding user attributes:

• Go to Configure OAuth tab. Scroll down and click on Test Configuration.
• You will see all the values returned by your OAuth Provider to WordPress in a table. If you don't see value for First Name, Last Name, Email or Username, make the required settings in your OAuth Provider to return this information.

• Once you see all the values in Test Configuration, go to Attribute / Role Mapping tab, you will get the list of attributes in the dropdowns.

4. Role Mapping [Premium]

• Click on "Test Configuration" and you will get the list of Attribute Names and Attribute Values that are sent by your OAuth provider.
• From the Test Configuration window, map the Attribute Names in the Attribute Mapping section of the plugin. Refer to the screenshot for more details.

• Enable Role Mapping: To enable Role Mapping, you need to map Group Name Attribute. Select the attribute name from the list of attributes which returns the roles from your provider application.
  Eg: Role

• Assign WordPress role to the Provider role: Based on your provider application, you can allocate the WordPress role to your provider roles. It can be a student, teacher, administrator or any other role depending on your application. Add the provider roles under Group Attribute Value and assign the required WordPress role in front of it under WordPress Role.
  
  For example, in the below image, Teacher has been assigned the role of Administrator & Student is assigned the role of Subscriber.

• Once you save the mapping, the provider role will be assigned the WordPress administrator role after SSO.
  Example: As per the given example, Users with role 'teacher' will be added as Administrator in WordPress and 'student' will be added as Subscriber.

Step 5: Sign In Settings

• The settings in the Single Sign-On (SSO) Settings tab define the user experience for Single Sign-On (SSO). To add a OneLogin login widget on your WordPress page, you need to follow the below steps.

• WordPress 5.7 and below
• WordPress 5.8
• WordPress 5.9 and above

• Go to WordPress Left Panel > Appearances > Widgets.
• Select miniOrange OAuth. Drag and drop to your favourite location and save.
