Re: Is there anything in the sssd RHEL server OS settings that performs LDAP binds or connections to AD every 30 mins?

So Trellix did not accept this as a bug in their healthcheck script.  We
put in a RFE with tem to do this healthcheck invocation  using setpriv or
su -c.  Which doesn't trigger the LDAP queries.

Now we have an open case with RH Tech Support on this.  Basically, when
sudo is invoked as root and we have early in the /etc/sudoers file:

root    ALL=(ALL)       ALL

and then later on in /etc/sudoers file we have:

## Read drop-in files from /etc/sudoers.
#includedir /etc/sudoers.d

then sudo should not be making  group membership queries to enumerate all
the various AD groups in /etc/sudoers.d/*  files.  which is triggering
multiple LDAP queries on thousands of servers -- all on the hour and
half-hour.
