Bug ID: 1857104
Summary: Using FreeIPA breaks IPv4/IPv6 flags for SSH
QA Contact: extras-qa(a)fedoraproject.org
CC: abokovoy(a)redhat.com, atikhono(a)redhat.com,
Target Milestone: ---
Description of problem:
If a client is configured using ipa-client-install then the -4 and -6 flags
stop working for ssh.
Version-Release number of selected component (if applicable):
Doesn't matter. Seen on RHEL 6 through 8, and on current Fedora.
Steps to Reproduce:
2. ssh -4 host.example.com
Connected via IPv6
Connected via IPv4
The bug is that sss_ssh_knownhostsproxy is configured on the client and that
command doesn't respect the flags given to ssh.
The issue affects all hosts, not just those part of the same FreeIPA domain.
A practical effect of this is that connections get rejected or misbehave
because of IP based rules in place for this connection.
