I recently created a second site collection 'within' my first/root site collection. i.e.
My primary site collection is found at:
and the second one is at:
When I go to Site Permissions for the primary site collection I can search for group names, such as
Customers, but when i try to find that same group in the second site collection I cannot find it (I get the red-underline, saying This entry was not found).
How can I access the primary site collection's groups from my second site collection?
I'm still researching, but wanted to ask the question sooner rather than later, as time of the essence.
