I still do not have a clear picture. Is it true that any scenario starts with one master and all others are replicas?
Yes, you start by installing the first master with ipa-server-install, and then create replicas with ipa-replica-install. Depending on the options you provide, you can configure (or not) additional services, such as CA, DNS, KRA etc... A given service can be present on 0 / 1 / n servers (for instance KRA is optional). For the configured services, we recommend at least 2 servers to provide redundancy.
The first instance of a service is not always configured on the first master. For example, you can setup the 1st master without KRA, setup a replica without KRA and later on decide to run ipa-kra-install on the replica. In this case the KRA service is running on the replica only (and we would advise to run ipa-kra-install on another node to provide redundancy).
When 2 servers provide the same set of services, they are equivalent and there is no distinction whether it was the first master or not. As Rob said, the only exception is CRL manager and renewal manager as only one node can hold this function at a given time. But this function can be migrated to another node (see [1] for the procedure).
What about AD trust? Does it have to be set up for each of the new servers? https://www.freeipa.org/page/Active_Directory_trust_setup does say so: "When planning access of AD users to IPA clients, make sure to run ipa-adtrust-install on every IPA master these IPA clients will be connecting to."
Then I guess it does.
Can anyone confirm this?
There are more explanations in this doc: [2]. A FreeIPA server can be trust controller, trust agent or standard server. The server needs to be either a trust controller or a trust agent to resolve AD users and groups.
Hope this clarifies, flo
