Hi Shameer

The users should not be able to see the course resources until they have enrolled in the course.

Can you check under the participants or Assign roles in the course to see whether the user is listed as a learner.

The default method for enrolment is internal enrolment which asks the question You are about to enrol yourself as a member of this course. Are you sure you want to do this?

This may have been answered Yes - If you don't want to have enrolments so open it is possible to restrict this to require an enrolment key to enrol in the course.

See http://help.totaralms.com/Enrolments.htm#Enrolments for the various metods of restricting enrolments.

If the person isn't enrolled and getting access to the resources then I may need to login to your system to see waht is going on.
