No continuation references for referrals returned for some search filters

• Key: DIRSERVER-806
• Type: Bug
• Status: Reopened
• Priority: Minor
• Assignee: Emmanuel Lecharny
• Reporter: Stefan Zoerner
• Component/s: core
• Affects Version/s: 1.0.1, 1.0
• Fix Version/s: 1.0.3

Environment

* ApacheDS 1.0.1 (SNAPSHOT)
* Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-b03)
* Windows XP Professional SP2

Description

I have created a referral entry below the example partition like this:

dn: cn=theReferral,dc=example,dc=com
objectclass: top
objectClass: referral
objectClass: extensibleObject
cn: theReferral
ref: ldap://someHost:389/cn=somewhere

Afterwards I have performed some searches in order to check whether ApacheDS returns a search result continuation reference. I used JNDI and set Context.REFERRAL to "throw" in order to check whether I get a ReferralException.

Case 1:
Base: dc=example,dc=com
Filter: (objectClass=*)
Scope: sub

=> ApacheDS delivers a continuation reference with the search result. I get an exception at the client.

Case 2:
Base: dc=example,dc=com
Filter: (cn=Nick Cave)
Scope: sub

=> Other than expected, ApacheDS does not deliver a continuation reference with the search result. No exception occurs.

Note that the only change is the filter expression.

I have created a JUnit testcase to demonstrate the situation. It has been successfully tested with other Directory servers (OpenLDAP, IBM, Sun). I'll attach it soon.
