Hi,
i have two free-IPA directories setup in multi-master replication. Both
are running on CentOS 7.2 with latest Software installed. Replication
between both IPAs is setup correctly and i am able to authenticate
against each of the two manually.
However, if i shutdown IPA1 and try to authenticate from oVirt 3.5.6.2
against IPA2 i can't login. Login is only working if IPA1 is
running (keep in mind that manual authentication against IPA2 is working).
In the dirSRV Error-Logfile nothing is logged, however i can see the
authentication in the access log from IPA2:

Any thoughts why i can't authenticate via oVirt against IPA2?
Can you please also share if there is some error in /var/log/krb5kdc.log
in IPA2?
Anyway, please migrate to new ovirt-engine-extensions-aaa-ldap, read
this[1] for more information.
