Hello Everyone,

I am looking into an odd case that I'm hoping for some insight into.

Out of hundreds of students taking an exam we have two instances of access 
being denied to a linked pdf.  The link eventually worked for both students, 
within about six minutes for one.  A commonality between the cases is that they 
appear to have reentered the course just prior to the pdf being unavailable for 
them.  It is unclear if this is another symptom or the cause.

At least one of the students encountered the following message:

"Access  : Browse resources
Resource : The PDF
Action : Access Denied

Sorry ...
This action is currently not authorized."

I am also seeing access denied messages for the resource/user combination in 
ssl_error_log

My current theory is that the students somehow reinitialized their role in the 
course while taking the exam.  This then resulted in them temporarily not 
having access to the pdf resource.


Potential complications:


-          This course has it's resources' links encrypted.

-          This course is restricting access by ip address using the next 
version's restricted list.

-          The resource being linked to is in the authoring space rather than 
the course space.  This doesn't normally cause any trouble, but I'm listing it 
in case it interacts with something else.

Thank you in advance,

Lee
