Ersin Er commented on DIRSERVER-709:
------------------------------------

Fixed here http://svn.apache.org/viewvc?rev=433408&view=rev and here http://svn.apache.org/viewvc?rev=433415&view=rev

The problem was due to JNDI as it accepts "" as a valid value during a attribute remove operation. Now we do skip "" values in change sets of remove operations.

> In a special case, removal of the objectClass attribute in a certain way does not cause an error (no exception occurs). The entry is unchanged (which is correct), thus this is only a minor problem from my point of view. Here it is:
> If one creates an entry like this:
> dn: cn=Kate Bush,dc=example,dc=com
> objectclass: top
> objectclass: person
> objectclass: organizationalperson
> objectclass: inetorgperson
> sn: Bush
> cn: Kate Bush
> and performs the following modify operation with JNDI
> ModificationItem delModOp = new ModificationItem(DirContext.REMOVE_ATTRIBUTE, new BasicAttribute("objectclass", ""));
> ctx.modifyAttributes("cn=Kate Bush", new ModificationItem[] { delModOp });
> the method call of modifyAttributes does not throw an exception. The expected retuirn code is 69 (OBJECT_CLASS_MODS_PROHIBITED). Note that the correct return code is provided by the server, if I perform this Java code:
> ModificationItem delModOp = new ModificationItem(DirContext.REMOVE_ATTRIBUTE, new BasicAttribute("objectclass"));
> ctx.modifyAttributes("cn=Kate Bush", new ModificationItem[] { delModOp });
> or if the entry looks like this:
> dn: cn=Kate Bush,dc=example,dc=com
> objectclass: top
> objectclass: person
> sn: Bush
> cn: Kate Bush
> I was able to create JUnit test cases both with JNDI and Nescape SDK for Java and will attach both of them later.
