- Verify that the Unified Access Gateway SAML metadata is added on the service provider and the service provider SAML metadata is copied the Unified Access Gateway appliance.
- (Optional) List of Object Identifier (OID) of valid certificate policies for certificate authentication.
- For revocation checking, the file location of the CRL and the URL of the OCSP server.
- (Optional) OCSP Response Signing certificate file location.
- Consent form content, if a consent form displays before authentication.
- In the admin UI Configure Manually section, click Select.

You can select multiple root CA and intermediate CA certificates that are encoded as DER or PEM. CRL Cache Size Enter the certificate revocation list cache size. The default is 100 Enable Cert Revocation Change NO to YES to enable certificate revocation checking. Revocation checking prevents users who have revoked user certificates from authenticating. Use CRL from Certificates Select the check box to use the certificate revocation list (CRL) published by the CA that issued the certificates to validate the status of a certificate, revoked or not revoked. CRL Location Enter the server file path or the local file path from which to retrieve the CRL. Enable OCSP Revocation Select the check box to use the Online Certificate Status Protocol (OCSP) certificate validation protocol to get the revocation status of a certificate.

What to do next
When X.509 Certificate authentication is configured and Unified Access Gateway appliance is set up behind a load balancer, make sure that Unified Access Gateway is configured with SSL pass-through at the load balancer and not configured to terminate SSL at the load balancer. This configuration ensures that the SSL handshake is between the Unified Access Gateway and the client in order to pass the certificate to Unified Access Gateway.
