红帽全球峰会第 40 章 Managing Hosts in IdM CLI
Learn about hosts and host entries in Identity Management (IdM), and the operations performed when managing hosts and host entries in IdM CLI.
40.1. Hosts in IdM
Identity Management (IdM) manages these identities:
- Users
- Services
- Hosts
A host represents a machine. As an IdM identity, a host has an entry in the IdM LDAP, that is the 389 Directory Server instance of the IdM server.
The host entry in IdM LDAP is used to establish relationships between other hosts and even services within the domain. These relationships are part of delegating authorization and control to hosts within the domain. Any host can be used in host-based access control (HBAC) rules.
IdM domain establishes a commonality between machines, with common identity information, common policies, and shared services. Any machine that belongs to a domain functions as a client of the domain, which means it uses the services that the domain provides. IdM domain provides three main services specifically for machines:
- DNS
- Kerberos
- Certificate management
Hosts in IdM are closely connected with the services running on them:
- Service entries are associated with a host.
- A host stores both the host and the service Kerberos principals.
