ZoomInfo - SSO configuration

Please note that this application has not been formally tested by Kelvin Zero Inc. It is provided solely as a reference guide. If you encounter any issues, kindly submit a ticket directly through the support desk.

This documentation provides a step-by-step guide to setting up Single Sign-On (SSO) for ZoomInfo using MPAS. SSO simplifies user authentication by allowing access to multiple applications with a single set of credentials. This integration enhances security and improves user experience across your organization

To set up Multi-Pass with  ZoomInfo, ensure you meet the following requirements:

- ZoomInfo admin rights

- MPAS Admin rights

- Make sure that all users intended to use SSO in ZoomInfo are registered in your IdP and have the necessary permissions to access ZoomInfo.

Important: Custom elements in URLs (like realm names) are case sensitive. Make sure to match the exact casing from your environment.
