# This script tests a bug where syncprov used on a glue database
# with a subordinate syncrepl consumer database looses a read-lock
# on the glue suffix entry when a modification is received on the
# syncrepl consumer.  The bug is only triggered when there is an
# active syncrepl consumers of the glue suffix entry.
