Step 3: User Attribute Mapping

• User Attribute Mapping is mandatory for enabling users to successfully Single Sign-On into WordPress using AWS SSO. We will be setting up user profile attributes for WordPress using the below settings.

Finding user attributes

• Once you see all the values in Test Configuration, go to Attribute / Role Mapping tab, map an attribute with a username that is unique for every user. You also map other attributes like firstname, lastname, etc. Click on Save.

Step 4: Role Mapping [Premium]

• 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 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 Contributor.

• 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 Contributor.

Step 5: Sign In Settings

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