Issue ID: 10362
           Summary: Normalised value confusions in replication
           Product: OpenLDAP
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Keywords: needs_review
          Severity: normal
          Priority: ---
         Component: slapd
          Assignee: bugs@openldap.org
          Reporter: ondra@mistotebe.net
  Target Milestone: ---
A lot of code expects a_nvals state to be consistent across modifies and
multiple instances of the same attribute (with asserts to that effect), but
replication doesn't seem to obey this:
Add this assert into syncrepl_diff_entry()[0] :
assert( ( old->a_nvals == NULL ) == ( new->a_nvals == NULL ) );
if ( old->a_nvals )
    assert( ( old->a_nvals == old->a_vals ) == ( new->a_nvals == new->a_vals )
);
You'll see many tests fail this, the first of which is test043.
