| Doc Text: |
In Red Hat Enterprise Linux 7.4, the default value of the UseDNS configuration option had been changed to "No". This change prevented OpenSSH from translating IP addresses to host names to be used in server configuration files and access rules of the authorized_keys files. However, it also broke existing installations until manually corrected. With this update, the default value of UseDNS has been changed to "Yes", and the default configuration is compatible with Red Hat Enterprise Linux 7.3 and older installations again.
