During load testing of a bind,add,search,delete request I noticed connections to the LDAP server we're being left open until the first full GC occured.

Upon further investigation I believe I have tracked the bug down.   I have tested with the new code and it is now closing the connections properly.

In the Class org.apache.jmeter.protocol.ldap.sampler.LDAPExtSampler
Method Name: addTest

old code:

        try {
            res.sampleStart();
            ctx = ldap.createTest(dirContext, getUserAttributes(), getBaseEntryDN());
        } finally {
            res.sampleEnd();
        }


new code:

        try {
            res.sampleStart();
            DirContext ctx = ldap.createTest(dirContext, getUserAttributes(), getBaseEntryDN());
            ctx.close();
        } finally {
            res.sampleEnd();
        }
