红帽全球峰会第 15 章 Kerberos PKINIT authentication in IdM
Public Key Cryptography for Initial Authentication in Kerberos (PKINIT) is a preauthentication mechanism for Kerberos. The Identity Management (IdM) server includes a mechanism for Kerberos PKINIT authentication.
15.1. Default PKINIT configuration
The default PKINIT configuration on your IdM servers depends on the certificate authority (CA) configuration.
| CA configuration | PKINIT configuration |
|---|---|
| Without a CA, no external PKINIT certificate provided | Local PKINIT: IdM only uses PKINIT for internal purposes on servers. |
| Without a CA, external PKINIT certificate provided to IdM | IdM configures PKINIT by using the external Kerberos key distribution center (KDC) certificate and CA certificate. |
| With an Integrated CA | IdM configures PKINIT by using the certificate signed by the IdM CA. |
