I am trying to place users in AD groups, which will not exist in the
IDVault, based on a concatenation of two values. Easy if the groups exist,
but the values used are dynamically growing in number.

So what I have in mind is to test:

Set LocalVariable GroupName = ValA + Val B
Test... does Group exist with cn ValA +Val B
No? Create group before processing user add.
Yes? Add member to pre-existing group.

The part I'm hung on at the moment is the test. Any ideas how/where to
implement this?
I hope I'm not having a brain-fart on a very basic process...
