Having Identity Manager create groups in AD that are Universal, not Global (like the default behavior is) can be an issue.
In the Subscriber channel under the Creation Rule, create a new rule. I called mine "Create Groups as Universal."
If class name = group, then set destination attribute value("groupType",class name="Group","-2147483640").
This now creates all groups as universal groups in AD. Just a little tip: if you use parent and child domains and want to have groups created, be universal so that you can add users cross-domain.
Note: This solution was tested in an environment with Netware 6.5 SP5 and IDM 3.0.
