How reproducible:
Always.

Steps to Reproduce:
#
# Setup
#
service sssd stop
echo "ldap_sudo_smart_refresh_interval = 10" >> /etc/sssd/sssd.conf
echo "ldap_sudo_full_refresh_interval = 30" >> /etc/sssd/sssd.conf
rm /var/lib/sss/db/*.ldb
service sssd start
# Wait for the service to really come up,
# see https://fedorahosted.org/sssd/ticket/1357
# Without this delay the bug won't reproduce
sleep 3
check_sudo() { su user1 -c 'sudo -u user2 true' 2>/dev/null && echo ALLOWED || echo DENIED; }
#
# Test
#
check_sudo
ldapmodify -x -h server -D 'cn=Directory Manager' -w Secret123 -a <<EOF
