Subject: [PATCH] MAN: Clarify that changing ID mapping options might require
purging the cache
https://fedorahosted.org/sssd/ticket/2252
Currently SSSD chokes when IDs of users change, we don't support ID
changes yet. Because some users were confused about the failures, this
patch adds additional clarification.
