[ovirt-users] free-IPA Multi-Master Authentication Problem

Fri Jun 3 15:44:49 UTC 2016

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?

Thanks
