  • Enter your website's absolute URL as Identifier (Entity ID) e.g.
  • Enter again your website's absolute URL as Reply URL (Assertion Consumer Service URL) e.g. This is where Azure AD will redirect the user together with the SAML response after the user signed in with Microsoft.
  • Leave the Relay State empty. The WPO365 plugin will determine where to redirect the user after successful authentication.
  • Enter your website's absolute logout form URL as Logout Url e.g.
  • Click Save to save your configuration.

Please note See for more information on support for single sign-out, which is supported by the PROFESSIONAL, PREMIUM and INTRANET editions of the plugin. 

User Attributes & Claims

Mapping (custom) claims to WordPress user profile fields is a premium feature that requires one of the following addons / bundles CUSTOM USER FIELDS, LOGIN+, SYNC or INTRANET.

For instructions on how to configure this synchronization of Azure AD user profile attributes to WordPress, please check this guide.

SAML Signing Certificate

The SAML response that the Identity Provider (= Azure Active Directory) will send to the Service Provider (= WordPress website) will be encrypted and must be decrypted by the WPO365 plugin before it's processed. The X509 certificate needed for this can be downloaded in this section of the SAML configuration. 

  • Scroll down to the SAML Signing Certificate section.
  • Click the Certificate (base64) link.
  • Save the file and change the file extension to .pem e.g. saml-response.pem.
  • The file will be needed once you will configure the WPO365 plugin's SAML portion.

The last section provides you with 3 links that are needed to configure the Identity Provider of the WPO365 plugin's SAML portion.

Plugin self-test

  • On the plugin’s Single Sign-on configuration page click Test + Save configuration.
  • A popup window will open and you’re reminded to optionally clear server-side cache (if you didn’t do so at the start).
  • Click Confirm and you’ll be automatically taken to the Plugin self-test page.
  • Alternatively, you can simply click Plugin self-test from the plugin's configuration menu.
  • Click Start self-test to check the current configuration and the plugin’s ability to sign a user in with SAML (and optionally an app-only access token).

As soon as the self-test is starting, the ‘Test mode’ will be activated. During this time the plugin is not protecting your website. The plugin will now try and sign in using Microsoft and you may be prompted by Microsoft to sign in. Please be aware that at no time your authentication input will be shared with (y)our website and or the plugin: All information you enter is only shared with Microsoft at all times!

  • Once the self-test is finished (during the self-test the page may be reloaded) you will see the test results. You can click on each entry in the list to view the full details incl. category, severity and a proposed resolution to fix the issue.
