Subject [jira] Resolved: (DIRSERVER-643) Netscape SDK: Adding an entry with two description attributes does not combine values.
Date Thu, 27 Jul 2006 23:50:15 GMT
     [ http://issues.apache.org/jira/browse/DIRSERVER-643?page=all ]

Emmanuel Lecharny resolved DIRSERVER-643.
-----------------------------------------

    Resolution: Invalid
      Assignee: Emmanuel Lecharny

After further investigation, this is not a ApacheDS bug, but more likely a NetScape bug.

I have added a Junit testCase to checkj that if we add two values to an existing attributes,
then those two values are correctly added and stored.

The code looks like :
...
        Attributes attrs = new BasicAttributes( true );
        Attribute attr = new BasicAttribute( "description", "a British singer-songwriter with
an expressive four-octave voice" );
        attr.add( "one of the most influential female artists of the twentieth century" );
        attrs.put( attr );
...

Note that we just create one single BasicAttribute. I suspect that in Netscape Ldap API, the
very same command try to put two BasicAttribute into the BasicAttributes, so that the first
one is just discarded (to be investigated by NetScape guys ;)

For us, everything seems fine, to be double checked.

> Here is a strange behavior, which I am only able to demonstrate with Netscape LDAP SDK
for Java (or compatible APIs like Sun or Mozilla). I create an LDAPEntry with two separate
LDAPAttribute objects for two description values in the LDAPAttributeSet. 
> ...
> LDAPAttributeSet attrs = new LDAPAttributeSet();
> LDAPAttribute ocls = new LDAPAttribute("objectclass", new String[] { "top", "person"
});
> attrs.add(ocls);
> attrs.add(new LDAPAttribute("sn", "Bush"));
> attrs.add(new LDAPAttribute("cn", "Kate Bush"));
>         
> String descr[] = {
>    "a British singer-songwriter with an expressive four-octave voice",
>    "one of the most influential female artists of the twentieth century" };
>         
> attrs.add(new LDAPAttribute("description", descr[0]));
> attrs.add(new LDAPAttribute("description", descr[1]));
> ...
> After creation, the outcome is an entry within ApacheDS with only one of the description
values: 
> dn: cn=Kate Bush,dc=example,dc=com
> objectclass: top
> objectclass: person
> cn: Kate Bush
> sn: Bush
> description: one of the most influential female artists of the twentieth century
> I attach the complete code as a JUnit test case. The code (and the test case) works with
other LDAP servers (Sun Java System Directory Server 5.2 for instance) as expected (entry
with two description values).
> I was not able to create a comparable problem with an add operation with JNDI. I assume
that the corresponding BasicAttributes class within JNDI and its LDAP provider combines/consolidates
the attributes on its own, which results in one attribute with two values.
