You should be able to set back a short hostname provided you check that
in /etc/sssd/sssd.conf you set ipa_hostname to the fully qualified name
in the appropriate domain section.

This will insure sssd (and therefor login) works.

SSHD may not like GSSAPI authentication unless you fool it by a hack in
libkrb5 setting ignore_acceptor_hostname true in krb5.conf in the
[libdefaults] section.

Most stuff should work this way, but cannot vouch for all kerberized
servers you may deploy on such a machine.
