D2L Brightspace LTI issue

by Tim Alderson -
Number of replies: 17
Tried to set up LTI (for the first time) today after upgrading to WW2.13.

I believe all steps were followed, but I keep getting the following error when attempting to open the WW page from within D2L.

Any help welcome.

Hi Tim,

This looks like standard debug information.
It helps diagnose problems with the connection.

Are the connections working ok? if so you can now turn debug off. 
webwork2/conf/authen_LTI.conf:
# set this to 1 to have LTI calling parameters printed to HTML page for
# debugging. This is useful when setting things up for the first time because
# different LMS systems have different parameters
$debug_lti_parameters = 1; 


set the value of debug_lti_parameters to 0;





This value can be overridden in localOverrides.conf and also in 


course.conf if it was set there at some point.

This output is expected if you have set "$debug_lti_parameters = 1;" in authen_LTI.conf, but I would expect this to be in addition to the WeBWorK page itself. Do you get any other error messages, or does it give you access to your WeBWorK course?

indicates that you have

Try setting that to 0. This is probably what you want in any case if you want to allow TA's and professors to enter webwork directly.

    


    
It also seems possible that the url that you are using from D2L is not exactly right and it is trying to access WeBWorK at an incorrect page, one with no content.

Tried setting $external_auth=0, but I am still getting the same error. 

Incidentally I had commented out the line $external_auth=1 (since this made it impossible to enter Webwork directly), so it had defaulted to 0 already.

I have checked the URL in D2L, and it points to the correct page. Reloading the landing page after clicking the Webwork link in D2L (i.e. the page with the error above) gives the conventional direct login page for the course).

I'm not sure what else to try here. At least the instructors can still populate their courses the old way for this term.

                                        If you have really set $external_auth=0 then I would expect the message:




about using external authorization to go away. The other error messages would stay. 





I would check very closely the url that you are entering into brightspace (perhaps check with Alex Jordan who also uses brightspace) -- it appears that you are not accessing a course homepage but the top level of webwork (which prints the site_info file message) or the login_page for the course. 





You can check the error log for webwork and see if it reports the path.

                                        A couple of things to check:


Look at the course login log (/opt/webwork/courses/[coursename]/logs/login.log). It may give you more info regarding what's going on.

  


  
In authen_LTI.conf, what do you have as $preferred_source_of_username? With Brightspace this will only work when set to "lis_person_contact_email_primary". Brightspace does not send the "lis_person_sourcedid" value, and the WeBWorK code is currently only written to recognize those two choices. On my server I have modified the WeBWorK code to allow the passing of the Brightspace username to WeBWorK. I can send you that file if you would like.

Have you entered something in the "Key" field on the Brightspace side? WeBWorK can't handle this being left blank.

I see from the log that you were able to at least attempt login. None of my attempts from within D2L are in the log.

So, I suppose this means it is an issue specific to the D2L here at UNB. I will contact the D2L team here to see if they have any suggestions.

At least I got something different this time. I had been using the Tool Provider settings. 
Now, using the setup you used I get the following error:

                                        That one's an easy fix. WeBWorK doesn't know what WeBWorK role to match with your D2L role of "Faculty".




Add the following line to the %LMSrolesToWeBWorKroles hash:


"Faculty" => "professor",





It looks like this was a recent change in D2L to calling instructors "Faculty". I'll change this in authen_LTI.conf.dist so that it is automatically recognized in future versions of WeBWorK. I haven't checked if they changed the title of the student role. Once you get it up and running as an instructor, make sure that students are able to log in as well.





A couple of housekeeping things:



  
  1. You don't need to check all of the boxes under security settings. I tend to select them all when testing. I believe the ones required are
    "Send user ID to tool provider"
    "Send user email to tool provider"
    "Send system role to tool provider"
    2. 
    
  2. You can work with your D2L team to set WeBWorK up as a tool provider for all of your courses. Then you will be able to use the tool provider settings. I created a wiki page with the instructions at http://webwork.maa.org/wiki/LTI-Advanced_Authentication_for_D2L. I just realized that there is no link to this from the main LTI wiki page. I'll update that this afternoon.

Can you report what was wrong and how it was resolved -- in case someone else has a similar problem and needs to describe what to look for to their D2L  IT people?

The cause/solution in our case was a combination of the following:


1. Add the following line to the %LMSrolesToWeBWorKroles hash: "Faculty" => "professor"




 2. When choosing the Security Settings as detailed at http://webwork.maa.org/wiki/LTI-Advanced_Authentication_for_D2L#.WacknNGQyHA ), 
"Send user ID to tool provider" does not appear in the list, instead select "Send LTI user ID and LTI role list to tool provider" (choosing system username or system Org Defined ID instead failed in our case). 


So the minimal check boxes are:
