-                Parses a X.500 distinguished name for the value of the
-                "Common Name" field.  This is done a bit sloppy right
-                 now and should probably be done a bit more according to
-                <code>RFC 2253</code>.

-           I've noticed that toString() seems to do a better job than
-           getName() on these X500Principal objects, so I'm hoping that
-           addresses Sebastian's concern.
-
-           For example, getName() gives me this:
-           1.2.840.113549.1.9.1=#16166a756c6975736461766965734063756362632e636f6d
-
-           whereas toString() gives me this:
-           EMAILADDRESS=juliusdavies@cucbc.com
-
-           Looks like toString() even works with non-ascii domain names!
-           I tested it with "&#x82b1;&#x5b50;.co.jp" and it worked fine.
