As Ludo wrote, OpenDS 2.0 got the Go this week. You can download it here, http://www.opends.org/promoted-builds/2.0.0/.
OpenDS 2.0 includes major improvements over OpenDS 1.0, with a much expanded server control panel, task support for recurring jobs like backup, assured replication, enhanced access control, extensible matching rules functionality, SASL support, schema files for LDAP-based naming on Solaris and OpenSolaris, improved security support in the installer, interop with the IBM JVM, wicked perfs, and more. Docs are at https://docs.opends.org/2.0.
Also, Sun OpenDS Standard Edition 2.0 offers the full support option when you go to deploy with 2.0. Sun documentation is at http://docs.sun.com/coll/2508.1.
