2. Completing Domino prerequisites for SAML
Complete the following Domino configuration that is required by SAML.

3. Importing and cross-certifying the IdP Internet certificate
When configuring Notes clients for federated login using SAML, the clients must trust the certificate used by the Identity Provider (IdP). Import the IdP TLS certificate into the Domino directory and cross-certify it.

4. Creating and replicating the IdP Catalog
Create the IdP Catalog (idpcat.nsf) and replicate it to any servers participating in SAML federated authentication. If you will enable Web, Notes, or Nomad federated login, also replicate it to the ID vault server.

5. Exporting a metadata .xml file from your IdP
Export a metadata .xml file from your identity provider (IdP). This file contains information about the IdP that enables Domino to accept SAML assertions from it.
