SAML SSO plugin with Synology C2 Identity

For those interested, the free (and paid) version of this good plugin works also with a Synology C2 Identity IdP, but not without some responsive and professional help from the plugin technical support to supplement Synology inaccurate documentation.

Here are Bhavesh recommandations to configure the Synology C2 Identity side of a SingleSignOn relation with a WordPress site :

Follow the steps outlined below:
1. Access your WordPress site and navigate to the?miniOrange SAML SSO plugin.
2. Locate and click on the “Service Provider Metadata” tab within the plugin.
3. In this section, you will find the?ACS URL?and?SP Entity URL?information.

Next, please proceed with the following changes in your IDP settings:
1. Replace the SP Entity ID in the IDP settings with the SP Entity URL collected from the “Service Provider Metadata” tab.
2. Replace the Single Sign-On URL in the IDP settings with the? ACS URL obtained from the “Service Provider Metadata” tab.

Also settings on both SP and IdP sides are easier done in English as localized translations are further misleading.
