Hi. It's a little strange, because I can easily attach clients (VMs) to the Microsoft AD domain. Only sometimes there are problems with connectivity, but I will solve this in two ways: add the DNS suffix or adds a static primary DNS, which indicates domain.
/etc/resolv.conf nameserver 172.30.30.253 # DNS and AD server nameserver 172.30.30.1 # Router - DHCP search szypa.net By the way, is also one strange thing: Every time when I inserted record "nameserver 172.30.30.253" to file "resolv.conf" from time to time the file is overwritten / changed (I have no idea how) and record "nameserver 172.30.30.253" disappears (just as you would in general not been added). *And in all this is the cause that generates the problem.* *So I think that the problem are solved, but i do not know how to resolve a problem with hidding configuration in /etc/resolv.conf* Regards, *Grzegorz Szypa* 2014-09-24 8:03 GMT+02:00 Martin Perina <mper...@redhat.com>: > 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 ov...@szypa.net due to > javax.naming.CommunicationException: szypa.net:389 [Root exception is > java.net.UnknownHostException: szypa.net].
