Red Hat Summit20.4. Authorizing the installation of a replica on an IdM client
When installing a replica on an existing Identity Management (IdM) client by running the ipa-replica-install utility, choose Method 1 or Method 2 below to authorize the replica installation. Choose Method 1 if one of the following applies:
- You want a senior system administrator to perform the initial part of the procedure and a junior administrator to perform the rest.
- You want to automate your replica installation.
When installing an IdM replica, the system verifies if the provided Kerberos principal has the required privileges, which includes checking for user ID overrides. As a result, you can deploy a replica using the credentials of an AD administrator that is configured to act as an IdM administrator.
- Method 1: the
ipaservershost group Log in to any IdM host as IdM admin:
$ kinit adminAdd the client machine to the
ipaservershost group:$ ipa hostgroup-add-member ipaservers --hosts <client_hostname> Host-group: ipaservers Description: IPA server hosts Member hosts: server.example.com, client.example.com ------------------------- Number of members added 1 -------------------------
참고Membership in the
ipaserversgroup grants the machine elevated privileges similar to the administrator’s credentials. Therefore, in the next step, theipa-replica-installutility can be run on the host successfully by a junior system administrator.- Method 2: a privileged user’s credentials
Choose one of the following methods to authorize the replica installation by providing a privileged user’s credentials:
-
Let Identity Management (IdM) prompt you for the credentials interactively after you start the
ipa-replica-installutility. This is the default behavior. Log in to the client as a privileged user immediately before running the
ipa-replica-installutility. The default privileged user isadmin:$ kinit admin
-
Let Identity Management (IdM) prompt you for the credentials interactively after you start the
