In an eDirectory-eDirectory connector I'm wanting to catch a rename
operation and revert the source object back to the name it just changed
from. Seeing as the operation typically has the old and new name I figure
that this should be possible.

So in a Subscriber Event Transformation policy I've created a rule which
check whether it's a User that is being renamed. The action will need to
include a Veto to prevent the rename operation from going through to the
other DS.

I realise that the other action should be to rename the source object, but
I'm having trouble figuring out what to specify in the 'Specify String' /
Argument Builder. I don't seem to see an obvious way to derive the previous
name from the current operation with the nouns & verbs.

Can someone suggest something for me to look at?
