Hi Ruchi,

I would recommend for you to have a full walkthrough on the CM Security Portal Documentation first as it contains comprehensive information on security configuration:

[https://help.criticalmanufacturing.com/operationguide/system-administration/security/security-portal/](https://help.criticalmanufacturing.com/operationguide/system-administration/security/security-portal/)

Regarding OpenID specific requirements, based on the documentation, you’ll generally need to ensure the following prerequisites are in place for OpenID Connect to work with the CM application:

- **An OpenID Connect Identity Provider (IdP):** You need to have a configured and accessible OpenID Connect compliant IdP (e.g., Azure AD, Okta, Keycloak).
- **Configuration:** Configure it on MES as defined in [https://help.criticalmanufacturing.com/operationguide/system-administration/security/security-portal/security-portal-configuration/security\_portal\_config\_securityportal/?h=2+oauth%2F%2F%2F/#openid-connect](https://help.criticalmanufacturing.com/operationguide/system-administration/security/security-portal/security-portal-configuration/security_portal_config_securityportal/?h=2+oauth%2F%2F%2F/#openid-connect).
- **Network Connectivity:** Ensure that the CM application server can communicate with your OpenID Connect IdP over the network.

Best regards,

João Moreira\*\*\*\*
