[ovirt-users] [ovirt 3.4.3] No KDC can be obtained for domain... after using engine-manage-domains edit

[Martin Perina]

Hi,

I looked at the logs and you have serious DNS problems:

2014-09-24 07:32:24,984 ERROR [org.ovirt.engine.core.bll.adbroker.GetRootDSE] (DefaultQuartzScheduler_Worker-15) Failed to query rootDSE for LDAP server ldap://szypa.net:389 due to szypa.net:389
2014-09-24 07:32:24,984 ERROR [org.ovirt.engine.core.bll.adbroker.DirectorySearcher] (DefaultQuartzScheduler_Worker-15) Failed ldap search server ldap://szypa.net:389 using user ovirt at SZYPA.NET due to javax.naming.CommunicationException: szypa.net:389 [Root exception is java.net.UnknownHostException: szypa.net]. We should try the next server

You cannot authenticate your users, because LDAP server ldap://szypa.net:389
cannot be resolved. Are you able to resolve szypa.net on you engine host?

This looks like that szypa.net domain doesn't exist at all. Do you really have
correct DNS configuration on engine host?
