Our group system requires that our LDAP servers
be up-to-date with grouper with no more than a few
seconds delay. To do that we run a separate process
that watches a grouper change log and updates LDAP.
That same process puts each update message, in the
form of a REST resource, onto a message bus. Presently
that is activeMQ. If we were doing this fresh today
I think we might use Amazon's SNS service instead.

Several clients pick up messages from the group
activity queue. One of them sends selected updates
to Google Groups - triggered by a group attribute.
Other clients update local membership caches.

For historical reasons much of the code is in c.
If you're interested in some of it I can probably
get you a copy.

We've been doing this for about eighteen months. I have permission to
distribute the code; it has to be pried from the grip of the programmers,
tho. I believe that the Univ of Washington has been doing this even longer;
Jim Fox is the contact. Both sites use a message bus to make Grouper changes
available to a variety of listeners. We're on Grouper 1.6, trying to move to
2.x this summer.

We're getting ready to decide if we want to provision [some] Grouper-managed
groups to Google Groups.

Has this been "done"? Are folks working on this? Thoughts? Comments?

Thinking PSP is the way to go these days...
