LTI 1.1. Strange 'role' parameter.

Pavel.Mazhnik70

A few days ago brightspace (we use partners.brigtspace) started to provide POST 'role' parameter with value:"urn:lti:instrole:ims/lis/Student,Student,urn:lti:instrole:ims/lis/Learner,Learner,urn:lti:instrole:ims/lis/Instructor,Instructor,urn:lti:instrole:ims/lis/Mentor,Mentor,urn:lti:instrole:ims/lis/Staff,Staff,urn:lti:instrole:ims/lis/Administrator,Administrator,urn:lti:role:ims/lis/Learner,Learner,urn:lti:role:ims/lis/Member,Member" during the LTI 1.1 connection.This value is observed in both students and administrators accounts. So it becomes impossible to distinguish administrator from the student on LTI Provider side.Is it some kind of mistake? Thank you!

Hi Pavel,

 

As of the July release, we will be sending both the context and institution role mapping of a user. In the past, we only sent the institution role mapping. This was noted in the PRN: https://community.brightspace.com/s/article/Brightspace-Platform-July-2019-20-19-7-Preview-Release-Notes-468315060.

 

Here is the 1.1 spec: https://www.imsglobal.org/specs/ltiv1p1/implementation-guide#toc-7.

 

It appears this user's role is mapped to both students and faculty roles under the IMS Configuration UI at the institution level (urn:lti:instrole = institution, urn:lti:role = context role, ie. course level).
