Re: How to do a sorted search using Apache Directory API
Hi,
Just to close this off in case anyone else has a similar problem, I found
that if, after installing the overlay, I also specify a Matching Rule ID
for the sort key, I get the ordering I want
> SortKey sk = new SortKey( "sn",
SchemaConstants.NUMERIC_STRING_ORDERING_MATCH_MR_OID);
Cheers,
Tamsin

Re: How to do a sorted search using Apache Directory API
Hi
Thanks for the reply.
I tried with both 1.0.2 and 2.0.0.AM2 with the same outcome.
The output from the Java code was as below (I just have a local ldap with a
few users for testing)
sn: Trainee
sn: Admin
sn: User
sn: Supervisor
I did not know about the slapo-sssvlv overlay, my LDAP knowledge is basic -
I am running OpenLDAP from the docker image openfrontier/openldap-server
I tried to install it - I successfully loaded the ldif below. Now when I
run the original code I get no results at all. If I remove the SortRequest
control from the SearchRequest it returns me the expected results.

Is this the correct way to install the slapo-sssvlv overlay? I am not sure
how to provide it's configuration sorry.
Thanks

That's fine.
I'm running the code below against OpenLDAP 2.4.40. I based the code on an
integration test for SortRequestControl. However, this code does not return
the entries in the order I expect (alphabetical by sn). Can you tell me
what I am missing?
Thanks for any help!
SearchRequest req = new SearchRequestImpl();
req.setScope(SearchScope.ONELEVEL);
req.addAttributes("*");
req.setTimeLimit(0);
req.setBase(searchDn);
req.setFilter("(objectclass=posixAccount)");
SortRequest sortRequest = new SortRequestControlImpl();
sortRequest.addSortKey(new SortKey("sn"));
req.addControl(sortRequest);
try (SearchCursor cursor = connection.search(req)) {
while (cursor.next()) {
SearchResultEntry se = (SearchResultEntry) cursor.get();
Entry entry = se.getEntry();
System.out.println("sn: " + entry.get("sn").getString());
}
}
First, which version of the API are you using ?
Then, can you provide the result you get ?
Last, not least, are you sure your OpenLDAP server has the slapo-sssvlv
overlay installed ?
If so, can you provide its configuration ?
How to do a sorted search using Apache Directory API
Hi,
I hope this is an OK question to post to the list.
I'm running the code below against OpenLDAP 2.4.40. I based the code on an
integration test for SortRequestControl. However, this code does not return
the entries in the order I expect (alphabetical by sn). Can you tell me
what I am missing?
Thanks for any help!
SearchRequest req = new SearchRequestImpl();
req.setScope(SearchScope.ONELEVEL);
req.addAttributes("*");
req.setTimeLimit(0);
req.setBase(searchDn);
req.setFilter("(objectclass=posixAccount)");
SortRequest sortRequest = new SortRequestControlImpl();
sortRequest.addSortKey(new SortKey("sn"));
req.addControl(sortRequest);
try (SearchCursor cursor = connection.search(req)) {
while (cursor.next()) {
SearchResultEntry se = (SearchResultEntry) cursor.get();
Entry entry = se.getEntry();
System.out.println("sn: " + entry.get("sn").getString());
}
}
