IMPORTANT: If the node is running puppet, you must stop puppet service in the host before this procedure, otherwise, puppet might attempt to reenroll it before you finish all tasks. The hostname of a system is critical for the correct operation of Kerberos and SSL.

Both of these security mechanisms rely on the hostname to ensure that communication is occurring between the specified hosts. Renaming a host in a FreeIPA domain involves deleting the entry in FreeIPA, uninstalling the client software, changing the hostname, and re-enrolling using the new name.

Additionally, part of renaming hosts requires regenerating service principals. Identify which services are running on the machine. These need to be re-created when the machine is re-enrolled.

Each host has a default service which does not appear in the list of services. This principal can also be referred to as the host principal. Identify which of the services have certificates associated with them. This can be done using the ldapsearch command to check the entries in the FreeIPA LDAP database directly:.

For any service principals in addition to the host principal , determine the location of the corresponding keytabs on server. aliases: name. List of host names to assign. If an empty list is passed all hosts will be removed from the rule. If option is omitted hosts will not be checked or changed.

To generate certificates for services, use either certmonger or the FreeIPA administration tools. Re-add the host to any applicable host groups. Official Fedora Documentation Procedure for renaming a host. There is no way to change the hostname for an IdM server or replica machine.

The Kerberos keys amd certificate management is too complex to allow the hostname to change. Create a new replica, with a CA, with the new hostname or IP address.

Official Fedora Documentation Procedure for renaming an IdM server. IPA Directory RBAC differs from host access control because while host access control provides access to hosts and sudo, IPA RBAC grants permissions to modify the directory itself.

User groups: desktop-support see: ipa group-show desktop-support. Role user accounts are generally accessed by sudo-ing from a regular user account. As a convenience, authorized personnel are allowed to sudo to a role account without inputting a passphrase.

While we could change the default values for these parameters, there would still be some risk of collision on hosts which are provisioned by a 3rd party prior to installation on our network s.

Login credentials for a regular account are considered private to that person and must not be shared with another person, including IT staff. Shell access to hosts may be authenticated using either ssh private keys stored within IPA or using a krb5 token.

Passphrase auth shall not be allowed for hosts. Passphrases are allowed for access to resources via HTTPS and client VPN connections. SSH public keys shall be managed centrally via IPA. an account used for controlling an instrument. Passphrase auth for shell access shall not be allowed.

There shall be an audit trail of which person s have accessed which role accounts. When it is necessary, the only allowed form of authentication is via krb5 tokens. krb5 credentials shall not be provided to biological persons.
