How did you setup the authentication. DId you use AAA or engine-manage-domains ? Do you *have* to use kerberos, or can you just use ldap? If you have no requirement to use kerberos, then I would just use simple AAA ldap. How are you load balancing the IPA servers? Does fail over work for other things? IE client machines connected to the IPA realm? On Tue, Jun 7, 2016 at 9:49 AM, Kilian Ries <mail@kilian-ries.de> wrote:
Indeed there was a faulty record for the IPA2 - i corrected that. Now the engine-log shows the correct ldap-address:

I'm still not able to login to oVirt via IPA2
krb5kdc and dirsrv-acces Log don't show anything new.

It looks fine, thanks. Looking at the oVirt log I see IPA server FQDN:
auth02.intern.customer-virt.eu.intern.customer-virt.eu
Looking at krb realm, I guess this should be - auth02.intern.customer-virt.eu
Do you use SRV records or did you pass --ldap-servers to manage-domains? If SRV, then you maybe misconfigured DNS, if --ldap-servers, you should edit configuration with proper FQDN.
Hello,
here is the krb5kdc log from IPA2:

Thanks for the hint with the LDAP-Provider, i'm trying to migrate as soon as possible.

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.
