Title: #100: Updation of sssd-ad man page for case when dyndns_refresh_interval < 60
Hi, thank you for your contribution. I would personally use different phrasing: "Note
that the lowest values possible is 60 seconds." or similar. What do you think is
better? One nitpick, you are missing a space before "Note".
