I was recently asked by a colleague whether or not it is possible to change Group Scope for AD Groups since the AD Plug-in for vCO doesn't give you any options for Global, Distribution, or Domain local. Upon reviewing the answer for this, I found that it also does not allow you to differentiate between creating a Security group vs. a Distribution group.
See my article here for my approach in creating this package:How to change AD:UserGroup Scope and Type
UPDATE: I had originally attached the solution package to this community thread, but it has somehow managed to be corrupted and no longer able to import to vRO when downloaded from here. As a result of that behavior, I have removed the bad file from this post here and put a good copy of the .package file on my blog article linked above.
