Some of the training available is about LDAP concepts and won't change much as new versions are rolled out.
For the DSEE 6 taylored trainings, they are being finalized but you can check periodically here http://www.sun.com/training/catalog/courses/?sort=code
and look for training code starting with DIR-.
I will try to go fishing for a date and will get back to you later next week.
cheers
