Thanks for the fix.
As I wrote initially I had already tried with registering the two
factories and got a ClassCastException.
I tried now with RC3 but as suspected I still get the same
ClassCastException:

I have the feeling that some link between DSML and codec is missing for
the (sort) control...

Hi,
I have an application running in an OSGi container that uses the LDAP
API and DSML parser and I would like to use the server side sorting
control.
When I send the following control...
<ns2:control criticality="true" type="1.2.840.113556.1.4.473">
<ns2:controlValue
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:type="xs:base64Binary">MAYwBAQCc24=</ns2:controlValue>
</ns2:control>
...I get an error: "sorted results control value is absent".

I saw that an OpaqueControl is created for the sort control. Debugging
I noticed that setEncodedValue is never called.

Looking into this I came across the control factories registered on
LdapApiService and saw that there are two implementations:
- DefaultLdapCodecService
- StandaloneLdapApiService
DefaultLdapCodecService is what is initialized in OSGi setup. I
noticed that DefaultLdapCodecService unlike StandaloneLdapApiService
does not register SortRequestFactory/SortResponseFactory. To try if
this solves the issue I registered the two factories but then I get a
ClassCastException:

I do not understand how the DSMLv2 parser works together with the LDAP
codec and start to wonder if the server side sort control is even
supposed to work at the moment.
- Is it possible that the parser for DSMLv2 does not support the
server side sort control?
- Should SortRequestFactory/SortResponseFactory be registered or is
there a reason why they are not registered on DefaultLdapCodecService
per default?
I would appreciate any hints to get this working.
Cheers
Claudia
