On Fedora 25, ipa-server-install crashes during IP address validation due to defective check for server IP addresses.
This actually never worked but the bug was uncovered by glibc update which removed dns and myhostname' fromhosts:` directive.
dns
myhostname' from
Steps to reproduce:
1.) pull in the latest freeipa-fedora-test-runner Docker image:
docker pull martbab/freeipa-fedora-test-runner:master-latest
2.) start the container
docker run -d -h master1.ipa.test -v /sys/fs/cgroup:/sys/fs/cgroup:ro --tmpfs /run --tmpfs /tmp -v /dev/urandom:/dev/random:ro martbab/freeipa-fedora-test-runner:master-latest
3.) run ipa-server-install inside:
docker exec $CONTAINER_ID bash -c 'ipa-server-install --debug -U -a Secret123 -p Secret123 -r IPA.TEST'
Expected result:
Installation works
Actual result:
Installation fails with the following traceback in debug mode:
