Description of problem:
(moslty copied from https://bugzilla.redhat.com/show_bug.cgi?id=1330431)

The current version of rubygem-rkerberos requires libkadm5clnt_mit.so.8. This is quite unfortunate as functions provided by this lib are not considered stable by upstream [1] and it may change with krb5 rebase. If it changes (what happened with RHEL-7.2 and with RHEL-7.3), krb5 has no other option than pretending that it is still providing the old version [2]. This is a very bad practice, IMHO.

In EL7.5, krb5 switched to provide libkadm5clnt_mit.so.11 and that makes rubygem-rkerberos uninstallable.

While the proper solution would be not depending on the kadm libs, a rebuild (as soon as EL7.5 buildroots are available for EPEL) would fix the issue for the users.

Version-Release number of selected component (if applicable):
rubygem-rkerberos-0.1.3-5.el7

How reproducible:
always

Steps to Reproduce:
% rpm -q --requires -p rubygem-rkerberos-0.1.3-5.el7.x86_64.rpm |grep kadm
libkadm5clnt_mit.so.8()(64bit)
libkadm5clnt_mit.so.8(kadm5clnt_mit_8_MIT)(64bit)

Expected result:
% rpm -q --requires -p rubygem-rkerberos-0.1.3-5.el7.x86_64.rpm |grep kadm
libkadm5clnt_mit.so.11()(64bit)
libkadm5clnt_mit.so.11(kadm5clnt_mit_11_MIT)(64bit)
