We are trying to setup JIRA to work with one of our suppliers. As our instance also contains issues and items that should not be visible to this supplier, I was wondering if someone could give me a hint on how to restrict access based on a label (or on any custom field if more appropriate).
We would like this supplier to be able to work only on issues with a given label.
I believe I should work with Issue-Level Security but I don't really know how to implement that. Any hint will be greatly appreciated.
