When doing a slapi_search_internal(), my plugin crashes if there is an ACL entry
for
sockurl=<whatever>.  In slapd/acl.c, line 751, it checks
conn->c_listener_url.bv_val,
but conn->c_listener is NULL (presumably this is because of entry via
slapi...).

If I take out the sockurl ACL entries, all is fine.
