If you want to use Security Assertion Markup Language (SAML) authentication, but do not have your own Active Directory (AD) deployed, you can provision Ping Identity® as the SAML Identity Provider (IDP)
NOTE: Port 8443 is required for browsers to post SAML assertions to a Web Security Service asset. Verify that this port is open on your gateway firewall devices.
Setup Ping Identity for SAML
In the first phase, set up SAML authentication in the Ping Identity console.
