It looks like the LDAP and SSSD backends do not clear the user and
host match flags the same way the local sudoers file backend does,
which is a bug.

Do you happen to have the "mail_no_host" sudoOption enabled?
If so, try disabling it and see if the behavior changes.

You can get some debugging info by adding a line like the following
to /etc/sudo.conf:

Debug sudo /var/log/sudo_debug sssd at debug

One of the lines in /var/log/sudo_debug should look something like:
