Hi Francesco
sorry for the latency...
There is a clear bug in the way we handle a filter like
(ObjectClass=top) in the search engine. As 'top' is never present in the
index - for obvious reason : *every* single entry has such an attribute
value -, the filter returns no candidate, so the encapsulating filter
evaluation simply stops :
(&(objectClass=top:[0])(cn=testLDAPGroup)) (note the [0] here).
The code that does that is :
private long getConjunctionScan( PartitionTxn partitionTxn,
BranchNode node ) throws LdapException
{
long count = Long.MAX_VALUE;
List<ExprNode> children = node.getChildren();
for ( ExprNode child : children )
{
if ( ( count == 1 ) && ( child instanceof ScopeNode ) )
{
// We can stop here
break;
}
annotate( partitionTxn, child );
count = Math.min( ( ( Long ) child.get( COUNT_ANNOTATION )
), count );
if ( count == 0 )
{
// No need to continue <----- Obviously a bad idea in
this very case...
break;
}
}
In your case, there is a workaround : changing your filter to be
"(&(objectClass=*)(cn=testLDAPGroup))"
I'll open a JIRA.
Thanks for the report and the test case !

Hi there,
I am upgrading Apache DS from 2.0.0.AM25 to 2.0.0 and experiencing some
troubles.
Hmmm, there is no such 2.0.0.
Ah, sorry, I was meaning 2.0.0.AM26 of course.
For example, this used to work fine (e.g. to find the group with the given cn)
previously:
ldapsearch -h localhost -p 1389 -D "uid=admin,ou=system" -x -W -b "ou=groups,o=isp"
'(&(&(objectClass=top)(objectClass=groupOfUniqueNames))(cn=lastGroup3ae5600a))' cn
Now this does not return any result; when I change the filter to
'(&(objectClass=groupOfUniqueNames)(cn=lastGroup3ae5600a))'
it works again.
Also
'(&(objectClass=top)(cn=lastGroup3ae5600a))'
is working fine; so it seems that top is somehow disturbing.
Any ideas? Thanks!
Do you have an env I can use to test that ?
Hi Emmanuel,
sorry it took so long to get something simpler to reproduce the problem.
I have assembled at
https://github.com/ilgrosso/apacheds
Just clone and run
mvn clean verify
The tests executed are
https://github.com/ilgrosso/apacheds/blob/master/src/test/java/net/tirasa/sample/apacheds/ApacheDSApplicationTests.java#L42
which runs with filter
(&(objectClass=groupOfUniqueNames)(cn=testLDAPGroup))
and finds the group, and
https://github.com/ilgrosso/apacheds/blob/master/src/test/java/net/tirasa/sample/apacheds/ApacheDSApplicationTests.java#L59
which runs with filter
(&(objectClass=top)(cn=testLDAPGroup))
and does not find the group.
The ApacheDS init is in
https://github.com/ilgrosso/apacheds/blob/master/src/main/java/net/tirasa/sample/apacheds/ApacheDSStart.java#L193
Thanks for your support.
Regards.
