Background:
- This is not an App Registration.
- The requirement relates to an Enterprise Application configured with Single Sign-On (SSO) using SAML.
- This SAML SSO uses a signing certificate with an expiry date.
- We would like to track this expiry date in Centreon so that we can plan for renewal and avoid any service disruption.

Questions:
- Is there a plugin pack, connector, or Centreon monitoring method that allows us to retrieve the expiry date of this certificate?
- If this is not supported natively, is there a method recommended by Centreon for monitoring it, for example via Microsoft Graph, an API, or a custom script?
- If specific development is required, could you confirm the most suitable approach for integrating this properly into Centreon?
We would also be interested in any documentation, configuration examples, or best practices on this subject.
Thank you in advance for your feedback.
