Map between Azure AD groups and WordPress roles

Use this guide if you want to configure mappings between Azure AD (security / Office 365 / distribution list) groups and WordPress roles using the PREMIUM or INTRANET edition of the WordPress + Office 365 plugin.

Before you start

  • You must already have configured the single sign-on capability of the WordPress + Office 365 plugin.
  • You must also already have configured the integration capability of the plugin.
  • You are a Global Administrator for your company’s Office 365 tenant / Azure AD directory (or have at least the ability to edit the Azure Active Directory App registration that was created previously when the single sign-on capability was configured).
  • You are an Administrator for your WordPress website.

App registration

  • In Azure Portal click the 'hamburger' (icon with three horizontal lines in the upper corner) to open the menu.
  • Navigate to Azure Active Directory > App registrations.
  • Select the App registration that you created when you configured the single sign-on capability of the plugin.

Token configuration

Please note that the information below only applies to older versions of the BASIC edition of the plugin. Since version 11.0 premium the premium extensions LOGIN+, SYNC and INTRANET will also  try to retrieve all the (Azure AD / Office / Distribution list) groups a user is member of from Microsoft Graph (because of the ID token's limited capacity of max. 200 groups). For the plugin to be able to retrieve all groups the user is a member of, you must configure the Integration portion of the plugin (see https://docs.wpo365.com/article/23-integration for the necessary configuration and below for the required permissions).

  • Click Token configuration from the 'App registration' menu on the left.
  • Click + Add groups claim.
  • Select Security groups.
  • Click Add.

Important There is limitation of the number of groups sent by Microsoft. If the user is member of a large number of groups, vital information may be truncated.

Please note Microsoft will not only send the IDs of the groups the user is direct member of but also the IDs of those groups that encapsulate groups he / she is a member of (nested groups).

API Permissions

  • Click API permissions from the 'App registration' menu on the left
  • Click + Add permission.
  • Select Microsoft Graph > Delegated permissions.
  • Scroll down to Groups and check
    • Groups.Read.All
  • Scroll down to Users and check
    • User.Read.All
  • Click  Add permissions.
  • Wait until Grant admin consent for … has become available, then click to grant consent for all users in your tenant to use this ‘App registration’.
Please note that it can take up to several minutes before the consent button becomes available and can be clicked. And even after that you may see a red warning that consent could not be granted. If you see this warning, please repeat the sequence and click to gran consent for all users in your tenant again.
After you clicked to grant consent please wait until any spinner has disappeared to ensure that consent has been granted.

Even after waiting for several minutes and all indicators showing you that consent has been granted, it may take a few more minutes before the App registration becomes fully functional and the ID token contains the upn, email, given and family name. If the Plugin self-test later on fails but you are convinced that you did everything right, then wait a few more minutes and repeat the self-test.

Delete all tokens

  • Navigate to the plugin's wizard WP Admin > WPO365 and click Integration.
  • Click Delete all tokens.
  • Sign out of your WordPress website.
  • Sign back in with Microsoft.

This step is needed to ensure that the plugin refreshes the access token previously retrieved so that the updated permissions are reflected in your personal access token that the plugin retrieves when you sign back into your website with Microsoft.

Create a mapping

  • Open (in a new browser tab) Azure Portal and click the 'hamburger' (icon with three horizontal lines in the upper corner) to open the menu.
  • Navigate to Azure Active Directory > Groups
  • Click the group you want to create a mapping for and from the Overview page copy the group's Object ID.
  • Navigate to the plugin's wizard WP Admin > WPO365 and click User registration.
  • Scroll down to (Group) Role mappings.
  • Paste the Object ID of group on a new line and to left of it select the WordPress role that the group should map to.
  • Click "+" to add the mapping.
  • Click Save configuration.

Replace or add user roles

Each time a user signs into your website, the plugin will verify whether mappings between Azure AD groups and WordPress roles have been configured. If this is the case, the plugin will update the user’s WordPress role(s) in one of the following two ways:
  • Replace (= delete) all existing roles and then add the new ones.
  • Add any possible new roles (default behavior)
  • Skip assign roles all together.

Perform the following steps to change this behavior.

  • Still at WP Admin > WPO365 > User registration, scroll down to User role(s) update scenario.
  • Select Add if you want the plugin (each time when the user logs in and mappings between Azure AD and WordPress roles are verified or when users are being synchronized) to add possible new WordPress roles but leave the old ones (recommended).
  • Select Replace if you want the plugin (each time when the user logs in and mappings between Azure AD and WordPress roles are verified or when users are being synchronized) to delete existing WordPress roles for a user and add new ones.
  • Click Save configuration.

Default role as fallback

The plugin is capable of assigning multiple WordPress roles to a user. By default it will try and add the Default role main site first and additionally try adding any role that maps to any of the Azure AD groups that the user is a member. So without any applicable mapping the user will at least receive the role that you configured as default one for the main site.

To change this default behavior and configure the plugin to only to add the  Default role (main site / subsite) when no other WordPress roles are otherwise assigned to a user, perform the following steps.

  • Still at WP Admin > WPO365 > User registration, scroll down to Default role as fallback.
  • Check this option.
  • Click Save configuration.
