We will soon. It's a must, as otherwise we may have big trouble with
concurrent reads and writes, but we want to go farther.

The idea is to add the support of

that caused it to trigger in the first place, or are there no guarantees, ie, one could have
a situation where the ldap operation succeeds but the trigger is never executed say due to
an ldap crash?
That's a completely different thing. Trigger can execute any kind of
modification or processing. But if a trigger is executed within a
transaction boundary, then if the trigger fails, we will just roll back

Keep in mind two things :
- we are still to finish the backend that will support transactions (ie,
- the trigger code is really experimental at this point.

In the near future, our roadmap is the following :
- finish the implementation of Mavibot (we have to add the cleanup of
pages that will never be used anymore. Currently, we have a backend
which grows without limit)
- implement
- cleanup the trigger code

There is a lot of work to be done ! (and of course, any help would be
appreciated ...)
