Strange User IDs when Using Moodle as an LTI Tool

Strange User IDs when Using Moodle as an LTI Tool

I use Schoology as an LMS.  For homework for my students, I have a Moodle site running and I publish the Moodle quizzes as an LTI tool.  Students access the Moodle quizzes through Schoology's External Tool function.  The whole process seems to work well, including the correct grade passback from Moodle to Schoology.  However, the students' exact user name is not getting passed correctly from Schoology to Moodle.  If I want to login to Moodle to view the attempt, I see something like "42753849::9e8a7c781f5c80a02a0cded932865849" for a user name for the student.  It would be helpful if I could see the actual user name that should be passed to Moodle from Schoology.  Any idea what might be going on here so I can try to diagnose this problem?

Hi MIke,

I've just encountered this same issue when testing LTI with Schoology and the solution is to add Moodle as an LTI tool on the Course Level and not on the Material/Resource Level.

You can follow the steps from the link below:
https://support.schoology.com/hc/en-us/articles/206401048-Course-Materials-External-Tools

Go to the "Setting Up LTI External Tool Providers in Schoology" section.


Hope this helps!

I noticed something similar with Canvas....when you add the LTI, there is a Privacy drop down box. If you pick "Anonymous", then you get the weird user names generated, but if you pick something else like "Public" or "Name Only", then the student names should show up properly.

Hope that helps!

Hello Joseph,

I am having the same problem with the Canvas-Moodle integration, but I do not have access to the Canvas settings and have to ask the administrators to change settings. Is the Privacy Drop-Down located in Canvas or Moodle?

Thank You,
Stan

Thanks for the help.  This does work well.  It appears that Schooogy is only prepared to send user info to Moodle if you have it configured at the course level in addition to at the activity level.  If only you didn't have to add each activity twice....oh well, at least it works.  Thanks again!
