Subject: [PATCH 54/55] sss_domain_info: add not_found_counter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This new counter should be used to track how often a domain could not be
found while discovering the environment so that it can be deleted after
a number of failed attempts.

Resolves: https://github.com/SSSD/sssd/issues/5528
