mod_proxy_html or mod_ldap cannot be updated or installed after updating to a RHEL 7 ELS httpd package

Issue

• We've enabled the RHEL 7 ELS repo and updated httpd successfully. But now we can't also update or install mod_proxy_html or mod_ldap. Attempts to install or update show errors like below saying an earlier httpd package is required for the mod_proxy_html or mod_ldap package it wants to install:

# yum install mod_proxy_html
