Bug 504817 - Handle LDAPv2 quoted RDN values correctly
    
    The bug fix for bug 438139 introduced a regression that causes the
    server to not handle LDAPv2 quoted RDN values correctly.  We were
    including the '"' characters used to contain an unescaped value in
    the actual value itself.
    
    The proper thing to do is to eliminate any '"' characters that are
    not escaped when we unescape the value.  I have tested this new fix
    with the oringinal issue from bug 438139 to ensure that it does not
    introduce a regression for that bug.
