How to add server into AD group

Hi there,

I am looking for the way how to add server into AD group using workflow "Add computers to group members".

I have deplyment workflow where server AD account is created and I know and can find the server in the OU, but in mentined workflow is used array as input and "AD_UserGroup" parameter "addElements" is return type void (void addElements(Object[] elemetns: all elements to add to the group)) - this is from API explorer.

Maybe right question is how to push this AD:Computer to the above mentioned array?

Any help is helpfull, thanks all.
