Ludo Poitou, Mazen Arakji, and Marina Sum worked together on an article about using OpenDS as the LDAP directory for the naming service on OpenSolaris. You will find the article at http://developers.sun.com/identity/reference/techart/opends-namesvcs.html.
Plans are also taking shape to get OpenDS available with OpenSolaris, so you will not even have to go through the 3-minute install.
