User ID is not being send in the launch request when username is selected as User ID

[xcompass]

From Bob Walker:

This is mapped in the LTI Definition in 'Data Settings' ->2 Personal Data: User ID=required by tool, Value to use for user ID=username (in this case).

This means that this LTI Tool needs the calling program to pass the logged in user_id, and the user_id is defined as the 'username' (other options are Student ID and BatchUID).

So Connect should be passing through the lowercase puid for staff and the student number for students (the value of the username field). However, all values except the username are being passed.

The text I provided is snippets from the Tomcat log files for FoMIDM, showing how the user_id is filled out when coming from our MedIT Blackboard and blank when coming from verf.
