it's not nearly that fancy: atm it does this:

- accept a configuration item that gives a command (in my case, a shell script)
- it triggers this command via forking a execve call, ie: it calls that 
script, in the background
- it passes the DN being modified
- it passes the type of operation
- it passes the old DN (MODRDN)

planned features:
- cn=config handling
- passing the attribute being modified (MODIFY)

possibly, i might pass all attributes and values of the modified DN


in my case, atm, i handle stuff via the shell script and decide if i do 
something for this modified DN or not.

Kind regards,

Maarten
