The original spec and tracker issue for cohorts (MDL-21781) both mention "synchronisation with external systems", but I don't see any code that does this. Does anyone know if it's still planned?
I really like the cohort sync functionality, and it's going to make life a lot easier for us when we move to Moodle 2, but I'd rather not be developing custom LDAP and database sync scripts if I can avoid it! If this feature is under development I'd much rather put the time into being involved in that somehow, if possible.
