If you use DNS SRV records then in the short term all you need to do is drop fried server from the list of SRV records and move on. In the short to medium term on the clients you'd want to check /etc/ipa/default.conf and /etc/sssd/sssd.conf for references to that dearly departed server and replace them with another server. You'll also want to terminate any replication agreements with it on any other masters otherwise changes will accumulate. The only difference between the very first master you install and all the others is that first one generates the CRL and manages CA renewal. See https://www.freeipa.org/page/Howto/Promote_CA_to_Renewal_and_CRL_Master I should mention that unless a master has actually created a user or group it has no DNA configuration so has no range of values to assign to POSIX users/groups. A clone is installed initially without a range and it fetches one the first time it needs it, from the master that created it. Of course, if that master is gone then problems ensure. rob > > ________________________________________ > From: freeipa-users-boun...@redhat.com [freeipa-users-boun...@redhat.com] on > behalf of Nathan Kinder [nkin...@redhat.com] > Sent: Saturday, April 11, 2015 4:57 AM > To: firstname.lastname@example.org > Subject: Re: [Freeipa-users] FREEIPA REPLICA - ITS USE AND HOW IT SHOULD > OPERATE WHEN PRIMARY FAILS > > On 04/10/2015 06:54 PM, Martin Chamambo wrote: >> Good day >> >> I have a freeipa primary server working as i wanted , no complex stuff has >> been setup yet except the basic service and sudo controls which is fine by >> me.
