Bug Description

Using freeipa 4.3.1-0ubuntu1 on Ubuntu 16.04 servers.

I have setup a FreeIPA master server with the following commands:

apt install freeipa-server

    ipa-server-install --setup-dns --mkhomedir --auto-forwarders \
      --no-reverse --hostname=ewserv-auth01-prod.unix.ewadmin.ch \
      --ip-address=192.168.251.51 \
      --ds-password='dspassword' --admin-password='adminpassword' \
      --realm=UNIX.EWADMIN.CH --domain=unix.ewadmin.ch \
      --unattended

On a different server, I'm now trying to setup a replica. The
connection tests are good, see replica-master-conncheck.txt and
master-replica-conncheck.txt.

But ipa-replica-install fails (see ipa-replica-install.log.txt):

    $ sudo ipa-replica-install -P admin -w adminpassword --domain=unix.ewadmin.ch --server=ewserv-auth01-prod.unix.ewadmin.ch --realm=UNIX.EWADMIN.CH --hostname=ewserv-auth02-prod.unix.ewadmin.ch
    …
    Client configuration complete.

    Run connection check to master
    Removing client side components
    Unenrolling client from IPA server
    …
    ipa.ipapython.install.cli.install_tool(Replica): ERROR Connection check failed!
    Please fix your network settings according to error messages above.
    If the check results are not valid it can be skipped with --skip-conncheck parameter.
    ipa.ipapython.install.cli.install_tool(Replica): ERROR The ipa-replica-install command failed. See /var/log/ipareplica-install.log for more information

In /var/log/ipareplica-install.log (attached as well), I find:

[…]
