Always qualify requests for admin in ipa-replica-conncheck
ipa-replica-conncheck connects to the master using an SSH command:
ssh -o StrictHostKeychecking=no -o UserKnownHostsFile=<tmpfile> \
-o GSSAPIAuthentication=yes <principal>@<master hostname> \
echo OK
The issue is that the principal name is not fully qualified (for instance
'admin' is used, even if ipa-replica-conncheck was called with
--principal admin@EXAMPLE.COM).
When the FreeIPA server is running with a /etc/sssd/sssd.conf containing
[sssd]
default_domain_suffix = ad.domain.com
this leads to the SSH connection failure because admin is not defined in
the default domain.
The fix uses the fully qualified principal name, and calls ssh with
ssh -o StrictHostKeychecking=no -o UserKnownHostsFile=<tmpfile> \
-o GSSAPIAuthentication=yes -o User=<principal> \
<master hostname> echo OK
to avoid syntax issues with admin@DOMAIN@master
