I have a use case for a small part number of users to be able to change
their own user name. I am stumbling on this so far. I can append a cn to
the "recipient" but I cannot replace the cn (I understand why I cannot do
this). My question is how can I initiate a rename of user cn from a
workflow?

I am pretty handy with JavaScript. A co-worker suggested using an
integration activity to write a web service call. I was hoping there is
an easier way.

Thanks!
