Description Namita Soman 2011-05-24 13:12:26 UTC

ipa-server-install has an option:
--no-host-dns         Do not use DNS for hostname lookup during installation

Install using:
ipa-server-install --hostname=ipaqa64vma.testrelm -r TESTRELM -n testrelm -p Secret123 -P Secret123 -a Secret123 --no-host-dns 

If I do not have an entry in /etc/hosts, my install fails with error:
 Unable to resolve host name, check /etc/hosts or DNS name resolution
