Description of problem:

When IP address of master does not resolve to its hostname, ipa-replica-install
fails.

Version-Release number of selected component (if applicable):

python2-ipaserver-4.4.0-4.el7.noarch

How reproducible:

Deterministic.

Steps to Reproduce:
1. Have setup where IP address of master as seen by replica does not match
master's hostname.
2. Run ipa-replica-install --server ipa.example.test --domain example.test

Actual results:

/etc/ssh/ssh_config not found, skipping configuration
/etc/ssh/sshd_config not found, skipping configuration
Configuring example.test as NIS domain.
Client configuration complete.

Unenrolling client from IPA server
Removing Kerberos service principals from /etc/krb5.keytab
Disabling client Kerberos and LDAP configurations
Redundant SSSD configuration file /etc/sssd/sssd.conf was moved to
/etc/sssd/sssd.conf.deleted
Restoring client configuration files
Unconfiguring the NIS domain.
nscd daemon is not installed, skip configuration
nslcd daemon is not installed, skip configuration
Systemwide CA database updated.
Client uninstall complete.

Removing client side components

Your system may be partly configured.
Run /usr/sbin/ipa-server-install --uninstall to clean up.
