An OCSP responder URL in an end-entity certificate is used to designate a server for certificate status checking. OCSP stands for Online Certificate Status Protocol, which is a method of verifying whether a certificate is valid or revoked in real time. An OCSP responder is a server that responds to OCSP requests from clients with the status of the certificate in question. The OCSP responder URL in an end-entity certificate points to the location of the OCSP responder that can provide the status of that certificate.

CRLs are lists of certificates that have been revoked by the issuing CA and should not be trusted by any entity. CRLs contain the serial number of the certificate that has been revoked, the date and time of revocation, and the reason for revocation. Revoked certificates are automatically placed on the CRL by the CA and the CRL is updated periodically. CRLs can be exported through various methods, such as HTTP, LDAP, or SCEP. Each local CA has its own CRL that is specific to its issued certificates.

REST API is a feature that allows FortiAuthenticator to integrate with an existing identity management system with the goal of authenticating and deauthenticating users into FSSO. REST API stands for Representational State Transfer Application Programming Interface, which is a method of exchanging data between different systems using HTTP requests and responses. FortiAuthenticator provides a REST API that can be used by external systems to perform various actions, such as creating, updating, deleting, or querying users and groups, or sending FSSO logon or logoff events.

FortiAuthenticator can help facilitate the process of replacing an existing RADIUS server by enabling learning mode in the RADIUS server configuration. This allows FortiAuthenticator to learn user credentials from the existing RADIUS server and store them locally for future authentication requests2. This way, FortiAuthenticator can gradually take over the role of the RADIUS server without disrupting the user experience.
