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

Wed Jun 15 06:28:31 EDT 2016

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?
