Further to my original posting,
Setting this up on a site with unique permissions has allowed me to see this in action. However, setting this up as a site which inherits permissions causes the problem mentioned in my original post.
In the site with unique permissions users are being added on a user by user basis for test purposes. However, on the main site we are using a group set up in active directory (so staff changes only need to be carried out one), and that group has been
given the learner permissions.
Does anyone know if there are issues in the use of AD with the learner kits permissions?
