Previously, an error in the kerb.conf file would produce a Kerberos error when attempting to add more than one domain to an environment. This has been corrected so that the .conf file does not prevent multiple domains from being added.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
For information on the advisory, and where to find the updated

Verified on SI27 clean install. I added 3 domains, and here is /etc/ovirt-engine/krb5.conf: [libdefaults] default_realm = QA.LAB.TLV.REDHAT.COM dns_lookup_realm = true dns_lookup_kdc = true ticket_lifetime = 24h renew_lifetime = 7d forwardable = no default_tkt_enctypes = arcfour-hmac-md5 udp_preference_limit = 1 #realms [domain_realm] qa.lab.tlv.redhat.com = QA.LAB.TLV.REDHAT.COM rhev.lab.eng.brq.redhat.com = RHEV.LAB.ENG.BRQ.REDHAT.COM ad2.rhev.lab.eng.brq.redhat.com = AD2.RHEV.LAB.ENG.BRQ.REDHAT.COM
