Limited logging makes troubleshooting difficult for complex issues, would be good to increase the verbosity of the logs.

Configurable verbosity is a potential option

Need to change the encryption mechanism to encrypt only the username and not the domain name to pass through SSO

by adding it to the configuration page

Why is this link broke?

http://projects.oscelot.org/gf/project/bb-basiclti/

For some reason the first time ComPAIR was added as a LTI Basic tool, all launch requests would send the wrong signature.

Creating a new entry for the tool with the same parameters resulted in working links.

Something must have happened that would cause the first entry for the tool to send different parameters in the launch request than the parameters it processed locally to produce the signature.

• encryption for roster
• decryption for grades

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.
