Dear Community,
I'd like to uninstall and reinstall IPA from a CentOS box because its easier than
reinstalling the OS completely.
We have a number of replicas, and this host is installed using ipa-client-install and then
ipa-replica-install.
To remove it, I backup some data like /var/kerberos/krb5kdc/{cacert.pem,kd*} and
/etc/httpd/conf/password.conf
and then run '/usr/sbin/ipa-server-install --uninstall -U
--ignore-topology-disconnect'.
I then sed '/Environment=K/d', '/ExecStartPre/d',
'/ExecStopPost/d' /etc/systemd/system/httpd.service
I recreate the host-account on another replica using ipa host-add, then ipa
hostgroup-add-member.
On the now-removed host, I do some housekeeping like restoring the backed up files and
then I run;
/usr/sbin/ipa-client-install \
--password=${otp} \
--mkhomedir \
--no-ntp \
--unattended \
--domain=realm.name \
--realm=REALM.NAME \
--ca-cert-file=/etc/pki/ca-trust/source/ca.crt
then
/usr/sbin/ipa-replica-install \
--dirsrv-cert-file=/etc/pki/tls/private/ipa.pkcs12 \
--http-cert-file=/etc/pki/tls/private/ipa.pkcs12 \
--dirsrv-pin=pwd \
--http-pin=pwd \
--unattended \
--no-pkinit \
--no-ntp
I seem to get the following keytab request problem followed by dirsrv failure. from
ipa-replica-install (4.6.4-10.el7.centos.3.x86_64). If I upgrade to
4.6.8-5.el7.centos.4.noarch.rpm, I get the same problem.[1]
On serverb, the host which receives the binding request for the reinstall, I get
permission denied the bind dn "" does not have permission in dirsrv error
log...?
Does anyone have any thoughts,
Cheers and many thanks in advance,
Rob
