Groups and Subgroups

Hi,

I’ve tried sub-groups but they don’t seem to work as I expect. Access rights seem to open up more extensively than I anticipated.

I also cannot find any documentation that describes the intended behaviour of sub-groups.

Please could somebody

a) point me to a resource that might describe how permissions and access rights follows when groups are members of other groups

or

b) provide a quick explanation if you are able.

With thanks and best wishes

Rob
