If you have your own identity provider (IdP) in your organization, you can integrate the SAML IdP with your organization in Control Hub for single sign-on (SSO). Cisco has tested following IdPs:
- Active Directory Federation Services (ADFS)
- Duo
- F5 Big-IP
- Google Apps
- Microsoft Azure
- OKTA
- PingFederate
- Shibboleth
- SimpleSAML
