Hmmm....

When I try to set the initiator from an automatically triggered workflow, to
anything else that the provisioning administrator I get an "Logged in user
is not a Provisioning Administrator" error.

I would really like to set it to "creatorsName" or "manager" or something
else.

I have also tried to map the value within the provisioning request itself,
but I must be doing something wrong, since it does not seem to have any
effect.

Something like "map [attribute] to flowdata.initiator" produces no visible
effects.
Mapping "[attribute] to initiator" fails. Probably because i've got not
"initator" object.

Where exactly should I inject the initiator to get it to work ?
