Hi Michael
Is this an additional set of jobs for current SMP users? If so we have do this by creating a role that has only has access to that folder, we normally go with READ and RUN Task but you will need Write if they need to edit, then remove all non admin roles from the permoissions . Then we add the AD group to the import and make that a member of the role.
If it is a new set of users that will only ever see these jobs you need to clone an existing role that can do the minimum you require and remove all unwanted permisions before adding the ad group to it.
We are jumping straight form 7.1 to 7.6 so can't give specifics from the 7.5 console as I haven't seen it
