I would like to know if I can use ForgeRock as login authentication for Kibana. Specifically, is ForgeRock compatible with any protocol that is supported by Kibana (LDAP, SAML, OpenID, etc)?
ForgeRock AM can serve as an Authorization Server (AS) for OpenID Connect or an Identity Provider (IDP) for SAML, and ForgeRock DS can be an LDAP directory for the LDAP authentication capabilities offered by Kibana.
Personally, I’d always lean towards the more modern solution of the available options, which in this case would be OpenID Connect (OIDC). While I have not integrated AM with Kibana, I suspect it is fairly straightforward and would be happy to help you figure it out.
