I have a group (group1) containing users.
In real life, this group is handled by two people (group1-leads).
I want group1-leads to be able to manage group1.
So I double-click on group1 navigate to the Managed By tab and change to group1-leads.
However when I click "OK", I get an error message telling me:
An object (User) with the following name cannot be found:
group1-leads... bla bla bla
How do I set a group in this field?
